Systems with console terminals:
—

The console terminal serial line cable plugs into the
printer/console connector on the back of the system
unit.

—~

The keyboard is connected to the console terminal, not
the system unit.

If a mouse is not supported, a mouse loopback plug is
required.

If internal drives are not supported, a shorter internal SCSI
cable connerts the panel SCSI directly to the system board
SCSI connectcr.

The DECstation 2100/3100 displays status and error
messages accompanied by a message number. Descriptions
of the status and error messages can be found in
Appendix D.

If your system does not display error codes, refer to
Running Extended Self-Tests Without a Functioning
Monitor. That section will help you to interpret the error
codes by using the LED displays. For more information on

Successful Powei-Up Self-Test Display

Each number in the second line of the power-up self-test
display corresponds to tests for specific hardware components.
The third line shows the size of the workstation’s memory.
While the third line is being displayed, the workstation creates
a bit map of all bad memory pages which is passed to the
worksystem software. Then the rest of the display appears.
The fourth line in the display indicates the version of the
system module console program. The fifth line contains the
workstation’s Ethernet address. The sixth line shows the size of
memory in hexadecimal format. Numbers 1 to 16 are different
languages from which you select the proper keyboard. At the

The LEDs are arranged in two groups of four and form a
binary display. When you initially turn on the workstation, the
DECstation 2100/3100 performs the power-up self-test and the
LEDs blink accordingly. If an error is detected, the workstation
halts on the LED code corresponding to the failed component.
Note the configuration of the display. Refer to the Interpreting
the Status LED Display section in this chapter to interpret the
status LED codes.

Running the Self-Test

The self-test is similar to the power-up self-test, except you can ‘
run this test any time you are at console prompt. The self-test
performs slightly more extensive tests and attempts to put any
SCSI devices connected to the workstation on-line. To run the
self-test:

Type (exactly):
test -a

You see the following power-up self-test display.

If an error occurs during the hardware tests, the test
stops and and two question marks (??) appear. Follow the
procedure described in Unsuccessful Power-Up Self-Test.
When the workstation completes the self-test, the console

prompt appears.

Note: You can also use the reset button to run the self-test. If
you use the reset button, the workstation performs the same
hardware tests as is done during the power-up self-test; however,
it does not perform any memory tests and the workstation will
attempt to place recognized SCSI devices on line.

Note what test failed. When errors occur, testing stops
at the test that failed. For example, if the testing stops
following the display of test code 5, then test number 5
failed. Refer to the Interpreting Self-Test Results section in
this chapter for details about interpreting the self-test.

If the monitor is not working, vou can observe the status LED
display during the self-test. If an error occurs, write down
the LED display configuration that appeared. Refer to the
Interpreting the Status LED Display section in this chapter to
determine what component failed.

Interpreting Self-Test Results
This section describes how to interpret the power-up self-test
and the self-test results.
If any test failed during the self-tests:

Check all external connections, cables, and power cords.

Make sure the mouse connector is seated properly, or if the
workstation is a server, the mouse loopback connector is
installed.

If you cannot locate an external problem, compare the code of
the test that failed during the power-up self-test or self-test
with those described in Table 1-2 and take the appropriate
action. Refer to Chapter 2 for instructions about running the
extended self-tests.

Boot Command

This command specifies a file from which the worksystem
software is loaded. The format for this command is:
boot [-f FILE] [-n] [ARG...]

The -f flag followed by the FILE parameter specifies the
file you want to use during a boot procedure. If you do not
specify the -f flag and a file, then the file specified by the
environment variable, bootpath, is loaded. Refer to the
printenv command section in this chapter.

The FILE parameter has the format:

device(controller,unit,partition)filename

The device indicates the device from which you booting
the worksystem software. Typical devices are rz for
~ hard disk, tz for tape, mop for network booting.

Extended Self-Tests

Overview
This chapter describes how to run and interpret the DECstation
2100/3100 extended self-tests. You can run two types of
extended self-tests; console and SCSI tests.

Note: Status and error messages are listed and described in
Appendix D. Probable FRUs are included in the error-code lists.

Console Extended Self-Tests

Run console extended self-tests to diagnose component and
subsystem malfunctions within the system unit. Tables 2-1
through 2-2 list all the extended self-tests and where you can
find their descriptions in this chapter.
In most cases, you use a monitor to run and display extended
self-tests. If the monitor is not working, you can observe the
status LEDs to get the test r¢suits. Refer to the Running
Extended Self-Tests Without a Functioning Monitor section
in this chapter for instructions about using the status LED
display.

You can run these tests in several different modes, depending
on the type of information you want. The test modes are
described in Table 2-3.

Diagnostic Aids
This section describes tools you can use when trying to isolate
DECstation 2100/3100 hardware faults.

Diagnosing Intermitient Failuies
If the vrorkstation you are testing is experiencing intermittent
errors, examine the ULTRIX error logs before running extended
self-tests. You can use the ULTRIX tools, uerf and netstat, to
trace some hardware errors. Refer to Section 8 in the ULTRIX
documentation set for details about uerf and Section 1 for
details about netstat. You can also refer to the floubleshooting
Commandsfor ULTRIX-32 Field
Service Pocket Reference Card.

Connecting an Alternate Console
If your system does not display error codes, refer to Running
Extended Self-Tests Without a Functioning Monitor. That

You can type the DECstation 2100/3100 console commands
from an alternate console through the printer/console connector
located at the back of the system unit. When you connect an
alternate console and enable the correct serial line, the same
text that appears on the DECstation 2100/3100 monitor appears
on the alternate console. If using a terminal as an alternate
console, you can use either the DECstation 2100/3100 keyboard
or the alternzte console keyboard to type commands. Figure 2-1
shows the printer/console connector location.

Printer/Console Connector Location

To connect an alternate console or printer to the DECstation
2100/3100, do the following:
1.

Plug the external device (terminal or printer) into the
connector closest to the video monitor cable. Note that this
connector requires a modified modular jack (this jack looks
like a regular phone connector, except that the tab is offset).

Using the original console, type:
enable tty(3)

Extended Self-Tests

Table 2-3.

Test Modes

Mode Name

Argument

Description

[No]Halt On Error

The command for this mode toggles
Halt On Error off and on. When set
to Halt On Error, the diagnostic test
sequence stops as soon as an error

is detected and reports the error
immediately. The remaining tests
in the sequence are not run. Use
this to save time when you expect
an error to occur early-on in the test

sequence. This is the default mode
when the workstation is turned on.
{No]Loop On Error

The command for this mode toggles
Loop On Error on and off. When
set to Loop On Error, the diagnostic
procedure runs again as soon as
an error is detected. This mode is
designed for debugging hardware
components using an oscilloscope in
a manufacturing environment. The
default mode when the workstation
is turned on is No Loop On Error.

Manufacturer/Debug

This mode runs the most detailed
check of all components. Some of the
tests can destroy data on customer
media. Select this mode if the User
mode diagnostics fail to isolate a
fault.

User

This mode performs a fast

check of the workstation. It is
a less comprehensive hardware
check than that performed in
Manufacturer/Debug mode. This
mode reports hard, gross errors.
This is the default mode when the
workstation is turned on.

Terminating Connectors

Depending on the mode in which you run the diagnostics, you
might need to install terminators or loopback connecters for
the DECstation 2100/3100 connectors. Table 2-4 describes what

terminators and loopback connectors to install for User and
Manufacturer/Debug modes. Appendix B lists the terminator
and loopback connector part numbers.

installing the Internal SCSI Loopback Connector

When running the SCSI t4 test, install a SCSI loopback
connector in the system unit SCSI connector. Do the following
to install an internal SCSI loopback connector:
s

Remove the system unit cover (refer to the Removing the
System Unit Cover section in Chapter 3 for instructions).

Disconnect the SCSI cable from the system module by
pushing the SCSI connector latches in opposite directions.
This releases the SCSI cable from the system module.

2-11

Insert the SCSI loopback connector into the system unit
SCSI connector. Make sure the side marked Side 1 is facing

the rear of the system unit. This ensures that the pins on
the loopback connector are properly aligned in the system
module SCSI connector.

Note: It is possible to insert the connector offset by tuwo pins. Be sure
that the connector covers all pins.

Running SCSI Extended Self-Tests

All SCSI tests first check which devices are on the SCSI bus. If ‘
the devices are not ready, the test attempts to put the devices
on line. An error message appears if the test cannot put a
device on line.

Note: Status and crror messages are listed and described in
Appendix D. Probable FRUs are included in the error-code lists.

These tests consist of canned device tests for RZ, RX, TZ, and
CDROM (RRD) class devices. The canned disk test writes
8Kbyte blocks filled with block address data to 100 or 200
random locations on the disk surface. It verifies the result by
read-back and buffer-compare.

The canned tape test writes alternate db6c and its complement
to the tape in the form of 512-byte tape blocks. The test writes
one block of data to the tape with parity checking enabled.
A read-back with parity and full data-buffer-compare is then
performed.

The CDROM disc tests require a test diskette for extended
mode and perform “controller only” hardware tests in user
mode. Two levels of SEND DIAGNOSTIC are invoked.

In user mode, all devices receive send diagnostic with a self-test
bit set in byte 2 of the command block. This test performs
off-line nondestructive testing of the device, usually involving
no writes to the media and testing only the controller hardware.
Invoking extended test sets self-test and unofl bits in byte 2 of
the send diagnostic command block. The extended test invokes
a detailed self-test of the device involving writes to diagnostic
cylinders of the disk or to installed scratch media.

For a read-only device, device-read .apability is checked.
Features such as ECC, parity fir.aware checksum, data-buffer
integrity, etc. are exercised in this read-only mode.

For all error messages, follow the advice of the error message.
Note:

If you use CTRL/C to abort a test, be sure to use the init and

scsi rs commands to reset the system before proceeding.

t1—Sll Buffer Test

This test module consists of two tests: SII Buffer Address test,
and SII Buffer Memory test.
Note:

You do not need a SCSI loopback connector or a SCSI

terminator when running this test.

The address test is a fast test that identifies potential
addressing problems with the SII buffer. The buffer is 64Kbytes
of 16-bit words addressed by a 16-bit address field. A “1” is
walked across this field while addressing locations 1, 2, 4, 8,
etc. The test also writes these locations with their address data.
For example, address 8 receives data 8. At the end of the pass,
each location is checked to assure that it contains its address.
In the buffer test, four patterns are written one-per-pass to

each of the 64Kbyte word locations. At the end of each pass,
the patterns are read back and compared. The 16-bit patterns
are 0x0000, Oxffff, Oxaaaa, and 0x5555.

t2—Sll Target Mode Test
The Target Mode test utilizes internal test features of the
SII to verify its ability to operate and respond in the target
mode of operation. The R2000 CPU chip emulates the initiator,
providing the stimulus to the SII through writes of the SC1 and
SDb registers of this device. The R2000 monitors chip response
by examining SC1, which is updated by the SII as it transitions
through SCSI bus phases.
Failures in this test mode are almost exclusively SII chip

failures. Refer to the ANSI SCSI specification, SII chip
specification, and PMAX functional specification for a more
detailed description of SCSI and the SII.
Note that a superset of the SCSI protocol called DSSI is used in
this test. It is in every respect similar in operation to SCSI. A
command and data packet is built in memory and transmitted
to the SII. The SII stores these packets in SII buffer memory
space for later examination by the R2000.
Note:

It is recommended that you use a SCSI terminator. You do not

need a SCSI lcopback connector when run 1 ; this test.

14—SCSl Loopback and External Drive Tests
These tests, with the aid of a loopback connector, check the
functionality of the SCSI bus drivers and control signals.
The loopback connector check consists of driving the SC1
register cut around the loop and receiving the result in the SDB
register.
Numerous patterns are then driven around the loop to
check the data drivers.

The external drive tests then check the functionality of the
target and initiator mode controi signal drivers. Nine bits are
driven around the loop. In the first half of the test, data plus
parity is tested. In the next half of the test, the control signals
are driven onto the data bus and sensed in the SDB register.

You must install a SCSI loopback connector in the SCSI
connector on the system module for this test; disconnect all
SCSI devices. The procedure for installing an internal SCSI
loopback connector is described in Terminating Connectors in
this chapter.
Note: To run this test you must set the mode to Manufacturer/Debug
mode. Refer to Selecting Test Modes in this chapter to change the test
mode manually.

SII Errors—Code 0x0bd

SII Timeout Errors—Code 0x0be

SII Target end Initiator Tests

SCSI Errors—Code 0x0bf

SCSI Bus Troubleshooting

SCSI Device Errors—Code 0x0d3

Sl Errors—Code 0x0bd
These errors are flagged primarily during the internal testing of
the SII in the target and initiator modes. They may also occur
during the external loopback test or during an SII chip setup
prior to performing a probe operation.
Those errors that indicate the inability of the SII register to be
set to a desired value, point to a general SlII subsystem failure

and require replacement of the system module as a last resort.

For external drive tests (extdrv), care should be taken that the

loopback is properly oriented and seated in the SCSI connection
on the system module.
In messages that contain numeric output, the notation aaaa
and eeee represent hexadecimal quantities denoting the actual
and expected values of the particular SII register referenced in
that message. Refer to the SII chip specification and the PMAX
functional specification for a detailed description of the SII.
.

Sl Timeout Errors—Code 0x0be
These errors occur during internal testing of the SII in the
target and initiator modes. The R2000 CPU is used to provide
stimulus to the SII as it is tested for its ability to perform
initiator and target roles.

All errors in this category point to the SII chip as the source of
trouble. For FRU this means replace the system module as a
last resort. It is recommended that the internal and external
SCSI cable be disconnected and the test be rerun after issuing

a hardware reset. A recurrence of these errors under this

Extended Seif-Tests

2-4.

condition points to the SII chip/system module as the source of
failure.

Sli Target and Initiator Tests

The SII SCSI interface chip provides a means of testing the
chip for the ability to support the initiator and target roles as
defined in the ANSI x131-1986 SCSI specification.
When tested as a target, the ability of the SII to drive those
bus signals required for target mode operation is checked. The
R2000 CPU is used as the initiator. The SC1 register of the
SII is used to set and monitor the bus signal state. Refer to
the SII chip specification and/or PMAY fi:nctions! specification
if a more detailed explanation of these modes and the SII is
required.

When tested as an initiator, the R2000 drives the appropriate
bits to set the SC1 register which then acts as the target device.
All SII registers are 16 bit quantities and all quantities
represented as xxxx are expressed in hexadecimal.
SCSI Errors—Code 0x0bf

This class of error is flagged when a SCSI protocol violation

is detected. For example, a change to an unexpected phase
during a bus transaction, or an unrecognized message passed
from target to host. It is also used to signal a general bus
failure during manufacturing mode of test. The meaning of
failures in the SCSI error class is specific to the error event and
possibilities are given with each error code explanation.
SCSI Bus Troubleshooting
Many of the errors reported in this class are flushed due to
an improperly initialized or synchronized device, faulty bus
drivers, or cabling/connector problems. In addition, during
new devire installs, incorrect jumpering or power sequencing
problems may hang the bus.

Extended Self-Tests

Hot reconfiguration of the system is not supported. When
installing new devices, the following power sequencing is
bW~

Power down the external peripherals.

recommended:

Power up the system box.

Perform “scs1 pb” to verity the confhiguration.

Power down the system box.
Install new devices as required.
Power up all external peripherals.

The following courses of action are recommended to clear/correct
the indicated error condition.

Reset the hardware using the back-panel reset. Retry the
operation.

Inspect interconnects, cabling, cable lengths, and proper
end of the line termination on any external SCSI devices.
If none, the supplied external SCSI terminator should
be installed on the system box. Also verify that each
peripheral box is receiving power.

Check the SCSI address space using the “scsi pb” command.
Verify that each installed device is correctly identified.
Devices that do not show may have the address incorrectly
jumpered. Check and resolve any address problems. Retry
the failing operation. If unsuccessful, go to the next step.
If the peripheral of interest is an external peripheral,
disconnect all external peripherals. Terminate the SCSI
bus with the supplied SCSI terminator. If an internal RZ
is installed, run the SCSI cd test (providing no user data is
present). If user data is preset, run “t s” in user mode. If
successful, go to step 6. Otherwise, go to step 5.

Extended Self-Tests 2-&5

Disconnect all internal RZs and execute “t s” in user or
manufacturing mode. Note that “t s” requires a loopback
in manufacturing mode. If you do not have the loopback,
execute scsi tl, scsi t2. scsi t3 which are the equivalent of
the manufacturing mode tests excluding the loopback test
(scsi t4).
If successful, reconnect one internal RZ device at a
time, paying attention to power, address jumpering
and cable orientation as you do so. Power up and run
“scsi c¢d” for each device as suggested in step 4. Replace
defective drives/cables as appropriate. If there are external
peripherals proceed to step 6.

Reconnect external peripherals one at a time, observing
proper termination rules. Reset and run the appropriate
canned test or “t s” in user mode, if user data is present.
Replace cables/drives etc., as indicated.

SCSI Device Errors—Code 0x0d3
Errors of this type generally occur during a device test
operation. They may specify the unready state of the device
such as not loaded, spun-up or on-line, which may be corrected
by rectifying the condition that caused the error status. The
error may also signal a more catastrophic event such as a
device hang or no response. Possible fault causes are given as
appropriate with each error message.

Extended Self-Tests

Running Extended Self-Tests Without a Functioning Monitor
If your monitor is not working, obtain the results of the
extended self-tests by observing the LED display on the back of
the system unit. Use the procedures previously described in the
Running Conscle Extended Self-Tests section in this chapter to
1T

Naavvaavay

[=1WNS
gy VLTS, TP

The LEDs are arranged in two groups of four and form a binary
display. As the DECstation 2100/3100 performs an extended
self-test, the LEDs blink accordingly. If an error is detected,
the workstation halts on the LED code corresponding to the
problem.

If using the status LED display instead of a monitor:

Terminate appropriate connectors. Refer to the Terminating
Connectors section in this chapter for instructions.

Using the keyboard, type the appropriate command to run
a particular extended-self test.

The LED display blinks as the various tests are performed.
Tests thai pass should not cause ihe LED dispiay to remain on
any code for more than 30 seconds.
Interpreting the Status LED Codes

Use Table 2-5 to determine where the error occurred and what
action to take next. The binary codes in the table refiect the
status LED display as viewed from the back of the system

Installing Add-on D SIM Modules

The add-on memory option is installed in increments of 4Mbytes and is implemented on two D SIMs. Add-on memory
installation considerations include the following:

Add-on D SIM memory modules are always installed in
pairs. (You can replace individual modules that fail.)

D SIM slot numbers are etched on the system board next to
the D SIM connectors as shown in Figure 3-8.

Slot numbers are etched in two groups; odd numbers 1 to
11, and even numbers 2 to 12.

—

Odd-numbered slots are bits 0-15 plus 2 parity bits.

—~

Even-numbered slots are bits 16-31 plus 2 parity bits.

The sequence of installation for each 4-Mbyte module pair is
shown in Table 3-4. For example, you install a D SIM module
pair in slots 9 and 10 to increase memory capacity from 16
Mbytes to 20 Mbytes.

Before installing add-on D SIM modules, do the following steps:
1.

Be sure that the system is working properly.

R2000 CPU Registers

This appendix contains information about the register data
displayed by the workstation when exception errors occur.

System Control Coprocessor Registers
Registers within the system control coprocessor provide the
path through which the virtual memory system’s page mapping
is examined and changed, and through which the operation
modes (kernel versus user mode, interrupts enabled or disabled,
cache enabled or isolated, caches normal or switched) may
be controlled and by which exceptions may be identified and
handled. This section describes each of these registers.
Table C-1 shows the numbering of the system control
COprocessor registers.

B '

The EntryHi and EntryLo registers provide a data pathway
through which the TLB is read, written, or probed. These
registers are loaded with relevant information when translation
exceptions occur. These registers are only present for
implementations with an on-chip TLB.
EntryHi Register

The EntryHi register is a 32-bit read/write register that is used
to access an on-chip TLB. When virtual addresses are presented
for translation, the 6 bits of the EntryHi register contain the
Process Identifier (PID) used to match the virtual address with
a TLB entry.
The EntryHi register also holds the contents of the high-order
32 bits of a TLB entry when performing TLB read and write
operations. When a UTLB miss, TLB miss, or TLB modified
exception occurs, the EntryHi register is loaded with the Virtual
Page Number and the PID of the virtual address that failed to
have a matching TLB entry.

The EntryHi register has the following format:
31

VPN is the Virtual Page Number (upper oits of virtual
address).

R2000 CPU Registers

C-3

Entrylo Regisier
The EntryLo register is a 32-bit read/write register that is
used to access an on-chip TLB. The EntryLo register holds
the contents of the low-order 32 bits of a TLB entry when
performing TLB read and write operations. The EntrylL.o
register has the following format:
31

PFN is the Page Frame Number (upper bits of physical

N, if set, indicates the page is noncacheable.

D, if set, indicates the page is dirty and writeable.

G, if set, indicates that the PID is ignored.

0 is unused (ignored on write, zero when read).

R2000 CPU Registers

sV, if set, indicates the entry is valid.

C-4

The Index and Randomn registers are used to access particular
entries in the TLB for reading or writing. The Index register
also identifies the matching entry when the TLB is associatively
probed. These registers are only present for implementations
with an on-chip TLB.

TLB Index Register

The TLB Index register is a 32-bit read/write register of which
six bits indexes an entry in an on-chip TLB. The high-order bit
of the register indicates the success or failure of a TLB probe
operation.

The TLB Index register is used to specify the entry in the TLB
affected by the TLB Readl and Writel instructions. The TLB
Index register has the following format:
31

P is set if the last Probe operation is unsuccessful.

Ind is the TLB Index.

0 is unused (ignored on write, zero when read).

TLB Random Register

The TLB Random register is a 32-bit read-only register of which
six bits indexes an entry in an on-chip TLB. The value of this
register decrements on each clock cycle of the machine, whether
the processor executes an instruction on the clock cycle. The
values range between a lower bound set by the number of TLB
entries reserved for exclusive use by the operating systems
(TLBWIRED) and an upper bound set by the total number of
TLB entries (TLBENTRIES). In the current implementation,
the lower bound is 8 and the upper bound is 63.

The TLB Random register is used to specify the entry in the
TLB affected by the TLBWRITER instruction. It does not need

to be read for this purpose; however, the register is readable in

order to verify proper operation of the processor. To simplify
testing, this register is set to the upper bound upon system
reset. The TLB Random register has the following format:

Bad Virtual Address and Context Registers
The Bad Virtual Address and Context registers are loaded with
the virtual address for which a translation exception occurs.
The Context register is specifically used within a fast, minimal
TLB exception handler (called the UTLB miss handler) for
rapid access of Page Table Entries (PTEs) from main memory.
The Context register are only present for implementations with
an on-chip TLB.

Bad Virtual Address Register
The Bad Virtual Address register is a 32-bit read only register
that displays the most recently translated virtual address that
failed to have a valid translation. The Bad Virtual Address
register has the foilowing format:

BadVAddr is the bad virtual address.

Context Register
The Context register is a 32-bit read/write register containing a
pointer into a kernel virtual PTE array. It is designed for use
in the UTLB miss handler, which loads TLB entries for normal
user-mode references.
The 19-bit BadVPN field in the register is not writeable. It
contains bits 30..12 (user-segment virtual page number) of the
BadVaddr register. Bit 31 is excluded because the UTLB miss
handler is only invoked on user-segment references. Normally,
it contains the VPN of the most recently translated virtual
address that did not have a valid translation.

The 11-bit PTEBase field is writeable and readable. It indicates
the base address of the PTE table of the currently executing

user process. The Context register has the following format.:

Status and Cause Registers
The Status and Cause registers provide a means to alter
operating modes and to identify the cause of exceptions.
Status Register
The Status register (SR) is a 32-bit read/write register that
contains the kernel/user mode , interrupt enable, and diagnostic
state of the processor. The SR contains a three-level stack
(current, previous, and old) of the kernel/user mode bit (KU)
and the interrupt enable (IE) bit. The stack is pushed when
each exception is taken, and popped by the Restore From
Exception (RFE) instruction. These bits may also be directly
read or written.
The interrupt mask field (IM) is an 8-bit field that controls
the enabling of each of eight external interrupt conditions. An
external interrupt is taken if interrupts are enabled, when
corresponding bits are set in both the interrupt mask field of
the SR and the interrupt pending field of the Cause register.
The actual width of this register is machine-dependent; see
the description below of the interrupt pending (IP) field of the
Cause register.
The Coprocessor Usability (CU) field is a 4-bit field that
individually controls the usability of each of the four coprocessor
units. Regardless of the setting of the cUy bit, coprocessor zero
is always considers usable when in kernel mode.
The Diagnostic Status (DS) field is an implementationdependent 12-bit field that is used for self-testing and checking
of the cache and virtual memory system. The Status register
has the following format:

CU control the usability of each of the four coprocessor
unit numbers (1 = usable, 0 = unusable). Coprocessor zero

is always usable when in kernel mode, regardless of the
setting of the cU, bit.

DS is an implementation-dependent diagnostic status field.

IM is the Interrupt Mask. It controls the enabling of
each of the external, internal, coprocessor, and software

‘

interrupts (0 = disabled, 1 = enabled).

KUo is the old kernel/user mode (0 = kernel, 1 = user).

IEo is the old interrupt enable (0 = disable, 1 = enable).

KUp is the previous kernel/user mode (0 = kernel, 1 = user).

1Ep is the previous interrupt enable (0 = disable, 1 =
enable).

KUec is the current kernel/user mode (0 = kernel, 1 = user).

[Ec is the current interrupt enable (0 = disahle, 1 = enable).

0 is unused (ignored on write, zero when read).

Diagnostic Status

The diagnostic facilities are heavily dependent on the

characteristics of the cache and virtual memory system on
the implementation, therefore, the layout of the diagnostic
status field is implementation-dependent. Its normal use is for
diagnostic code, and in certain cases, for use by the operating
system diagnostic facilities (such a reporting parity errors),
and on some machines, for relatively rare operations such as
flushing caches. In normal operation, this field should be set to
zero by operation system code.

‘

The diagnostic status bits: BEV, TS, PE, CM PZ, Sw(C, and
IsC provide a completed fault detection capability, but are not
intended to provide for extensive fault diagnosis.
The SwC bit controls the switching of control signals for
instructions and data caches associated with the processor.
When the bit is changed, cache control signals are altered so
that instruction and data caches are effectively interchanged.
The processor must be executing from an uncached region and
must not be executing loads or stores near the time of cache

switching.

C-10

R2000 CPU Registers

‘

The IsC bit, when set, causes the cache currently being used
as the data cache to be effectively isolated from the rest of
the memory system, making cache diagnostics possible (The
selection of the data cache is dependent on the state of the
SwC bit). When the IsC bit is stet, store operations atfect
only the cache (main memory writes are inhibited), and load
operations return the data at the addressed location in the
cache, whether a cache miss occurs (main memory reads are
inhibited). Uncached data references are not generally useful
with IsC set, but their handling is as follows: uncached store
operations affect neither the cache nor the main memory
system, and uncached load operations return the data at the
addressed location in the cache. IsC affects only data reference;
instruction fetches are not affected. This bit may also be used
by operating system code to flush caches without causing
associated main memory accesses.
The PZ bit, when set, causes zero to replace the normal
outgoing parity bits which are generated on a store instruction,
covering both cache data and tags. This permits the writing
of incorrect parity bits in the caches, checking each parity tree
individually within the cache diagnostics.
The CM bit, when the cache is isolated, indicates whether or
not the most recent data cache load resulted in a cache miss.
This bit is used by cache test programs to verify the proper
functioning of the cache tag and parity bits.

The PE bit indicates whether a cache parity error occurred. It
is set on a cache parity error and reset by writing a one to this
bit. Writing a zero to this bit does not affect its value. This bit
is used to log cache parity errors in software, as ot' erwise,they
are recovered from completely transparently. Within cache

diagnostics, this bit is used to verify proper functioning of the
cache parity bits and of the cache parity trees.
The TS bit is read only and indicates that the TLB has shut
down due to attempts to cause several entries in the TLB
to be accessed simultaneously. This mechanism protects the
TLB from hardware failures in the event of catastrophic
software misuse of the TLB. When the TLB is in this state,
all translations and PROBE accesses are inhibited, and have

R2000 CPU Registars

C~11

undefined effects. This state can be cleared only by asserting
RESET.

The Bootstrap Exception Vectors (BEV) bit, when set, causes

‘

the UTLB miss exception vector to be relocated to a virtual
address of 0xbfc00100 and the general exception vector to
0x80000080 (general), respectively. This bit is used when
diagnostic tests cause exceptions to occur priscr to verifying
proper operation of the cache and main memory system.

Cause Register

The Cause register is a 32-bit read/write register that describes
the nature of the last exception. a 4-bit exception code indicates
the cause of the exception and the remaining fields contain
detail information relevant to the handling of certain types of

R2000 CPU Regis

C-12

('n'

exceptions.

‘

The Branch Delay (BD) bit indicates whether the EPC was
adjusted to point at the branch instruction which precedes the
next restartable instruction.

The Coprocessor Error (CE) field indicates, if the exception is
"Coprocessor Unusable”, the coprocessor unit number reference
by the instructions which cause the exception.

The Interrupt Pending (IP) field indicated which external,
internal, coprocessor, and software interrupts are pending.
1P;; may be written into to set or reset software interrupts.
The remaining bits, IP;5 are read only , and represent external,
internal, or coprocessor interrupts.
The number and assignment of the IP (and IM) bits are
implementation dependent. The R2000 processors have six
external interrupts, where IP5 is used for the MIPS FloatingpHint coprocessor interrupt. IP2 is normally used for system

bus (I/0) interrupts. The Cause Register has the following

Exception Program Counter (EPC)
The EPC register indicates the virtual address at which the
most recent exception occurred. This register is a 32-bit read
only register that contains an address at which instruction
processing may resume after servicing an exception. For
synchronous exceptions, the EPC register contains the virtual
address of the instruction which was the direct cause of the
exception. When that instruction is in a branch delay slot, the
EPC register contains the virtual address of the immediately
preceding branch or jump instruction.

C-14

R2000 CPU Registers

If the exception is caused by recoverable, temporary conditions
(such as a TLB miss), the EPC register contains a virtual
address at the instruction which caused the exception. Thus,
after correcting the conditions, the EPC registers contains a
point at which execution can be legitimately resumed. The EPC
register has the following format:
