INTRODUCTION

Page 1-2

The first step in microprogramming the WCS is the creation of the
microprogram. To do this, you write the microprogram in MICR02 source
language and create a source file (.MIC).
Then, you assemble the
microprogram to create a listing file (.MCR) and an object file
(.ULD). MICR02 detects as many errors as possible in the source
microprogram.
You correct the errors and reassemble until you are
satisfied with the resulting microprogram.
When you are ready to test the microprogram, you load it into the WCS
using the microprogram loader, MICLD. You can then transfer to the
microprogram by executing an XFC instruction in a main memory program.
This manual describes
assembling,
loading,
and
executing
a
microprogram for the VAX 11/780 WCS. Some information on debugging a
microprogram can be found in Appendixes C and D of the VAX 11/780 Data
Path Description (AA-H307A-TE).
A macro language for microprogramming the VAX 11/780 is given in
Appendix A.
This language, called the VAX 11/780 Predefinition
language, defines the fields of the microword and a set of macros for
performing the logical functions associated with microprogramming the
VAX 11/780. A VAX 11/780 microprogram written in this definition
language is given in Appendix B.

CHAPTER 2
ASSEMBLING YOUR MICROPROGRAM

MICR02 is a general purpose tool, written in BLISS,
that executes
under user control in the VAX/VMS environment. The MICR02 language
lets you express the actions of a microprogram symbolically.
The MICR02 assembler translates a microprogram written in its source
language to the bit representation that is loaded into the Extended
wcs. In doing this, it performs syntactic checks on the program and
issues messages if the source microprogram is not valid.
Further, MICR02 allocates any microwords that you do not specifically
allocate.
You can allocate a microword absolutely, specify a
constraint on its allocation (such as the two lowest order bits of the
address must be zero), or leave the allocation to MICR02.
The following sections provide a quick reference to the MICR02
language and its use. A complete description of the MICR02 assembler
is given in a separate document:
MICR02 User's Guide/Reference Manual (AA-H531A-TE)
The MICR02 User's Guide/Reference Manual is a tutorial, which contains
many examples of the use of the MICR02 language.

2.1

PROGRAM STRUCTURE

The MICR02 assembler is a line-oriented processor, which accepts a
sequence of input lines written in MICR02 source language and produces
a listing file and an object module.
The input to MICR02 is a source program. A MICR02 source program can
contain one or more memories. The bit-numbering direction and the
program radix apply to the entire program.

Page 2-2

ASSEMBLING YOUR MICROPROGRAM
2.1.1

The Bit Numbering

The .LTOR and .RTOL keywords define the way in which the bits of a
microword are numbered, so that MICR02 knows whether to count from the
left end or the right end of the word to locate a bit position.
The
form of the bit-numbering keyword-line is the keyword itself, namely:
• LTOR
.RTOL
The .LTOR keyword directs MICR02 to consider the bits of the microword
numbered from left to right.
The .RTOL keyword directs MICR02 to
consider the bits numbered from right to left.
If no bit-numbering keyword is given, then .LTOR is assumed.
MICR02 uses the first .LTOR or .RTOL keyword it finds to establish the
direction in which the bits are numbered and ignores any subsequent
bit-numbering keywords in the program.

2.1.2

The Program Radix

The program radix is set by either the .OCTAL or .HEXADECIMAL
keywords.
The form of the .OCTAL and .HEXADECIMAL keyword-line is
simply the keyword itself, as follows:
.OCTAL
.HEXADECIMAL
MICR02 uses the first program radix keyword it find
subsequent program radix keywords in the program.

Memories

A program can include data for as many as 26 memories. Except for the
bi~-numbering
convention and program radix, which can be specified
only once in a program, all other constru~ts are considered to belong
to a memory.
Each memory has its own address-space, word-width,
field- and macro-definitions, and microinstructions.

The beginning of a section of the memory is

that
memory-indicator and up to the end of the program or another
memory-indicator are associated with the specified memory.

2.1.4

The Program Title

The .TITLE keyword-line supplies a title for MICR02 to use as part of
the heading of the output listing.
MICR02 reproduces the quoted
string following the .TITLE keyword as part of the first line of the
output listing. The .TITLE keyword-line has the following form:
.TITLE "title-string"

2.1.5

The Table of Contents

The .TOC keyword-line supplies a subtitle and adds an entry to the
table of contents.
MICR02 reproduces the text given in quotes
following the .TOC keyword as part of the second line of the page
heading of the output listing.
The .TOC keyword-line has the
following form:
.TOC "text-string"

2.1.6

Field Position

The left-bit and right-bit are decimal numbers that identify the
beginning and end bits of the field
in the microword.
If you
specified right-to-left bit numbering,
then the left-bit must be
greater
than
or
equal
to the right-bit.
If you specified
left-to-right bit numbering, then the left-bit must be less than or
equal to the right-bit.

2.2.3.1 The .DEFAULT Qualifier - The .DEFAULT qualifier specifies a
value that MICR02 can use for a field when the field is not explicity
set.
The form is:
.DEFAULT = expression
In forming a microword, MICR02 begins with a word consisting of all
zeroes,
sets the fields explicitly set in the microinstruction, and
then applies defaults. MICR02 uses a default for a field if and only
if no bit of the field is set explicitly.
In applying defaults, MICR02 uses the order

In addition to designating the associated field as a jump field,
the
.NEXTADDRESS qualifier specifies that the default for the field is the
value of the address associated with the next microinstruction given
in the program.

A number
An expression name
A function call
A field value name
A field contents indicator
A predefined symbol
The following sections consider each of these cases in detail.

2.3.1

Numbers

MICR02 recognizes integers or decimal numbers.
An integer
is
interpreted according to the program radix. A number with a decimal
point is always interpreted as a decimal number. The program radix is
set by either the .OCTAL or the .HEXADECIMAL keyword.
If a program
radix is not given, then an octal radix is assumed.

2.3.2

Expression-Names

An expression-name is defined by the .SET keyword as follows:
.SET/expression-name = <expression>

2.3.3

Function Calls

MICR02 provides functions for comparison, arithmetic, and Boolean
operations.
Also, MICR02 provides functions to detect parity, shift,
and select a case from a set of choices.

it must
qualified by the field-name when used in an expression as follows:
field-name/value-name

Page 2-9

Field Contents Indicators

The contents of a field can be designated in an expression by giving
the field-name
followed by a slash.
For example, to find out if the
current contents of field B contains the value 4, you write the
following expression:
.EQL [,<4>]

2.3.6

Predefined Symbol Names

The following symbols are predefined in MICR02, as follows:

2.4

Symbol

Meaning

• (period)

The address of the current
microinstruction

MACROS

The macro capability of MICR02 permits the definition of a
representation for a microprogram at a higher level than the basic
field-value pairs.
Once the fields of your microword are defined, a
set of macros that set groups of fields appropriately for certain
operations can be specified.
Macros cannot generate more than one
microinstruction.

2.4.1

The Macro-Name

Macro-names are formed using the set of characters given in Section
2.2.1.
In addition to these characters, MICR02 recognizes square
bracket pairs and commas in macro-names as indicators of the number
and position of the macro parameters.
The number and position of parameters in a macro-name are an integral
part· of the name.
(That is, the macro ABC[][] is not the same as
ABC [,] • )

2.5

THE MACRO-BODY

The macro-body consists of any combination of field-settings and
macro-calls
separated by commas.
When a macro is used
in a
microinstruction, MICR02 replaces the macro-name by the macro-body
associated with that name.

ASSEMBLING YOUR MICROPROGRAM
2.5.1

Page 2-10

Parameters

Square brackets and commas indicate parameters in the macro-name. The
character "@" followed by a decimal integer in the macro-body
indicates the position of the parameter in the macro-body.
This
character pair is called a parameter-designator.
The decimal integer in the parameter-designator refers to
the
position, numbering from left to right, of the parameter in the name.

2.6

MICROINSTRUCTIONS

The microinstructions describe the processing to be performed by the
microprogram.
These microinstructions are expressed in terms of the
field- and macro-names defined.
For each microinstruction, MICR02
translates
names
into
the
appropriate sequence of bits and creates the associated microword.
The microinstruction contains the information MICR02 needs to set the
bits of the microword.
A microinstruction begins with an absolute address assignment, one or
more labels, or both. Following this optional information, a sequence
of field-settings and/or macro-calls is given separated by commas.
That is, the form of the microinstruction is:
address:
{ label: }
{ field-setting }
{ macro-call
}

' .. .

Both the address and label can be omitted.

2.6.1

Continuing A Microinstruction

If a microinstruction occupies more than one line, the separator
character ',' must be as the last non-blank character of all lines
except the last line. For purposes of this discussion, the end of the
line is assumed to be either the ';' character, which begins a
comment, or the actual end of line. Thus the last non-blank charact~r
of a line means the last non-blank before the ';' or end of line.

THE MICROWORD

MICR02 creates a microword in the following way:

2.8

MICR02 begins with a word of the specified length
each bit has a value of zero and a status of unset.

in which

MICR02 then fills in all the fields that are
in the microinstruction.

Then, MICR02 sets any fields that have an associated
and that contain only unset bits.

Then, MICR02 evaluates any VALIDITY expressions.

Finally, MICR02 performs any parity adjustment indicated.

explicitly

set

default

THE ADDRESS SPACE

The .REGION keyword determines the address-space. The .REGION keyword
is followed by one or more pairs of address limits, as follows:
.REGION/low-bound,high-bound •••
Low-bound and
according
to
any number of
low-bound and

high-bound are expressions whose values are interpreted
the program radix. An address-space thus can consist of
address-ranges.
An address-range is specified by the
high-bound.

Any number of .REGION keyword-lines can be given.
MICR02 allocates
the microinstructions following a
.REGION up to the next .REGION
keyword (or the end of memory) in the specified address space.
If a .REGION keyword-line is not given at the beginning of a memory,
MICR02 assumes that the address space begins at O and ends at MAXPC,
the highest available address for the given architecture.

2.9

SPECIFYING THE METHOD OF ALLOCATION

Within the specified address space, either sequential
allocation (or some combination of both) can be used.

2.9.1

random

Sequential Allocation

In sequential mode, MICR02 allocates a microinstruction by taking
address of the previous microinstruction and adding 1.

the

ASSEMBLING YOUR MICROPROGRAM

Page 2-12

MICR02 begins allocating with the first address in the address space
defined by the .REGION keyword and continues incrementing until it
reaches either an absolute address assignment or the end of an
address-range.
When it reaches an absolute address, MICR02 uses that address for the
associated microinstruction and as the new base for incrementation.
When MICR02 uses th~ last instruction in an address-range, it chooses
the
first
address
in
the
next address-range for the next
microinstruction. After MICR02 uses the last address in the last
range, it uses the address 0000 and issues an error message for each
word allocated following the last legal allocation.

2.9.2

Random Allocation

In random mode, constraints can be given to select a set of addresses
based on the low order bit configuration. Constraints are described
in detail in the next section.
MICR02 first allocates all absolute assignments and constraints and
then allocates the remaining microinstructions starting at the first
unallocated address in the first address-range
and
continuing
sequentially through the unallocated addresses of the address space.

2.9.2.1 Constraints - Many microprogrammable microprocessors perform
conditional branching by ORing some logic function into the low order
bit position of the next microinstruction address. MICR02 provides a
constraint
capability
for
generating a set of addresses for
conditional branching.
A constraint consists of an "=" character followed by
string composed of a sequence of 0 and 1 characters.

constraint

A constraint specifies a set of addresses.
In response to a
constraint string, MICR02 chooses a base address that satisfies the
low order bit configuration specified by the constraint. The bits of
an address are always ordered from right to left. So the low order
bit is the right-most bit.
MICR02 then assigns the next n microinstructions to the addresses
formed by systematically increasing the base address counting only in
those bits designated as O's in the constraint string.

ASSEMBLING YOUR MICROPROGRAM

Page 2-13

2.9.2.2 Indicating a bit that can be 0 or 1 - In addition to O's and
l's, the character '*' can be used in a constraint string. This
character informs MICR02 that it can select an address that has either
a O or a 1 in that position for the base address.

2.9.2.3 The size of the address set - The number of
microinstructions in the set, n, is determined by the number of zeroes in the
constraint string, as follows:
n=2**X
Where X is the number of O's in the constraint string.

2.9.2.4 Constraints Within Constraints - If
MICR02
encounters
a
constraint string within the set of instructions it is allocating to
the block of addresses associated with an outer constraint string, it
skips to the next. address satisfying the inner constraint and then
proceeds according to the algorithm specified by the outer constraint.
The purpose of the nested constraint is to skip over some addresses
that would otherwise be allocated by the outermost constraint.

2.9.2.5 Terminating a Constraint - A null constraint within the scope
of the constraint terminates the constraint. A null constraint is the
"=" character. A constraint can also be terminated by an absolute
address assignment;
however, in this case, MICR02 issues a warning
message.

2.10

COMMUNICATION

In MICR02, communication among memories in the same program
communication among separate programs can be accomplished.

2.10.1

and

Memory Communication

Each
memory
has
its
own
definitions,
identification,
and
address-space.
However, if the same field-name is defined in more
than one memory, then the value-names defined for that field in any
memory are known in all other memories that define the field. This
feature permits communication between memories.

MICR02 contributes to the associated file.
If the counter is a
negative number, MICR02 does not contribute.

The List Control Counters

If a list control counter
is positive,
then MICR02 creates the
specified part of listing.
If a list control is negative, MICR02
suppresses the specified part of the listing.
The counter associated with the .• LIST and .NOLIST control determines
whether or not an output listing is produced.
The counter associated
with the .BIN and .NOBIN controls determines whether or not the object
part
(left field) of the listing is produced. The counter associated
with the .CREF and .NOCREF controls whether or not names will be added
to
the cross reference map. The use of the MICR02 assembler in the
VAX environment is described :ln the following sections.

THE VAX 11/780 DEFINITION LANGUAGE

The VAX 11/780 Definition Language describes the VAX 11/780
architecture and provides a macro language for writing microprograms.
A listing of this definition is given in Appendix A; the source for
the definition language is available on a floppy in the VAX 11/780 WCS
kit.
This file (VAXDEF.MIC) is copied to SYS$LIBRARY when the user
WCS tools are installed on a system.
You can express the actions of a microprogram in the macro~ given in
the definition language.

CHAPTER 3
LOADING A MICROPROGRAM

MICLD is a BLISS program that runs under user control in the VAX/VMS
environment.
MICLD loads the object files (.ULD) produced by MICR02
into the Extended Writable Control Store.
MICLD requires kernel (CMKRNL) and error logging (BUGCHK)
privileges.
It uses VAX privileged registers and
instructions to load the
microprogram into the WCS and to report the WCS load in the system
error log.
To use MICLD,
therefore, you must have privileges to
execute in kernel mode.

FUNCTIONS

The following sections consider each of these functions in detail.

3.1.1

Verifying the Installation of the Extended WCS Board

MICLD first checks that the Extended WCS Boa·rd is physically and
operationally present in the system.
If MICLD finds that the Extended
WCS Board is not installed, it issues an error message and exits back
to the operating system.

LOADING A MICROPROGRAM
3.1.2

Page 3-2

Initializing the Extending WCS

If MICLD finds that the Extended WCS is properly installed, it then
initializes each word of thE~ Extended WCS, starting at 1800 and
continuing through lFFF (1C00 through lFFF if G&H is present) to an
initialization pattern.
You can specify the initialization pattern for MICLD to use by
including the file qualifier /INITIAL, as described in Section 3.3.
If you do not specify an initialization pattern, MICLD uses the
default pattern given in Figure 3-1.

Default Initialization Pattern

Bits 0 through 12 of the def.ault initialization pattern contain the
address of the microword in the WCS being initialized.
Bits <47:42>
contain a two (2) to guarantef~ that no reads or writes will occur to
the main memory should the microword inadvertently be executed.
All
other bits in the 96-bit wide microword are set to 0.
After execution of MICLD, any microaddress not explicitly loaded
contains the initialization pattern.
If a microprogram mistakenly
jumps to a word that contains the default initialization pattern, then
the execution of that word causes a branch to itself with no-op
function.
The machine then loops at that instruction, continuing to
branch to itself.
Thus,
if your program branches to an unexpected
address, you get both protection and information.
To recover control
from this microcode loop, you enter the console "INIT" command while
the console is in console command ~ode.
If the console is not in
console command mode, entering Control-P at the console will get it
there.
If a microprogram gets into an instruction loop as described
you must manually reboot the system and then reload the WCS.
3.1.3

above,

Setting the Starting Address

The entry vector (VAX address 10E0 hex) must be set to the address at
which the microprogram in the~ Extended. WCS begins.
MICLD sets the
entry vector to an address if an /ENTRY qualifier is given in the
command line.
If an address i:s given with the /ENTRY qualifier, MICLD
interprets that address as a hexadecimal number and uses that number
to set the entry vector.
If an address is not given, then MICLD uses
the address of the first microinstruction in the ULD file to set the
entry vector.

LOADING A MICROPROGRAM

Page 3-3

If an /ENTRY file qualifier is not given, the entry vector must be set
by using the console program or the privileged instructions before the
execution of the microprogram is attempted.
The entry vector is
discussed further in section 4.1.2.

3.1.4

Loading the Microprogram

MICLD loads the microwords· specified in the ULD file.
MICLD begins by
creating an image of the loaded wcs.
It initializes this image to the
initialization pattern and then reads the ULD files, starting with the
first word in the first file and continuing sequentially until the
last word of the last file.
Each entry in the ULD file for a microword contains both the address
of the microword and its contents.
MICLD uses the address to
determine the position within the image in which the contents of the
word is to be stored.
When MICLD finishes reading the last word of the last file,
the created image sequentially into the control store.

loads

MICLD permits over-writing. That is, it lets you load an address more
than once. When MICLD loads a word into any address, it checks to see
if the address has been loaded previously.
If so, MICLD issues a
warning message and then loads the new word into the given address,
destroying the previous contents.
If you take advantage of the over-writing capability of MICLD,
you
must be careful about the order in which you specify files when you
call MICLD.
If you do not over-write the WCS, then you can specify
your files in any order.
MICLD issues a message at the end of the loading
whether or not the loading was successful.

3.1.5

process,

indicating

Logging the WCS Load

Each time MICLD runs successfully, it makes a note in the system error
log that the WCS contents has been changed. These notes can help the
system manager determine which user microcode is in the WCS, or relate
system problems to particular pieces of user microcode.

LOADING A MICROPROGRAM
3.2

Page 3-4

VERIFYING THAT THE LOADING WAS SUCCESSFUL

It sometimes happens that, dUE! to a hardware malfunction, the WCS is
not properly loaded and MICLD is not able to detect that fact.
The
WCS is a write-only memory and MICLD, thus, cannot verify its contents
by reading it back after loading and comparing its actual contents
with its expected contents.
Erratic or unexpected performance-of the executing microprogram can
indicate that the WCS is not properly loaded. However, such behavior
can also mean that the microprogram is not completely debugged.
Under
these circumstances, you can try to validate the loading process by
one of the following methods.

3.2.1

Using The Sample Program

One way to try to validate the loading process is to load and execute
a program whose behavior is known. The sample microprogram given in
Appendix B can be used for this purpose. A command file that uses a
test program to verify the installation of the tools and the loading
process is included in the VAX 11/780 WCS kit.
To invoke this command file in the VMS environment, type:
@[SYSEXE]WCSTOLTST
This command file assembles the sample microprogram (BSERCH) given in
Appendix B utilizing the VAX Definition Language given in Appendix A.
It then loads the resulting object file into the extended WCS and
executes the sample assembly language test program (BSTEST) given in
Section B.4. BSTEST executes an XFC causing the loaded sample program
to be executed.
After execution of the microprogram, control returns to BSTEST.
If
the microprogram executed properly, BSTEST prints the following
message on the terminal:
"Successful Test Completion"

3.2.2

S~quencing

With The Debugger

Another way to validate the loading process is to invoke the WCS
debugger from the VAX console and single step the microprogram.
You
can then observe if the correct sequence of address is executed.
The
debugger
is described
in 1\ppendix D of the VAX 11/780 Data Path
Description.

LOADING A MICROPROGRAM

Page 3-5

Since the WCS is a write-only memory, the debugger is not able to read
its contents. You must create a floppy disk image of the contents of
the wcs,.
The debugger then gives the illusion of reading the WCS by
reading
this floppy disk image that contains the microwords loaded
into the WCS.
Under normal circumstances, this method of operation is
effective.
However, the debugger cannot be used to validate the
loading process except, as described above, by sequencing through the
microprogram.

MICLD loads the files you give in the order specified.
If you

3.4.1

VAX-11/780 WCS Architecture Description

The Extended WCS is 96 bi ts wide by 2K occupying VAX addresses 1800
(HEX) through lFFF. The WCS is divided into three 32 bit X 2K pieces,
termed banks.
These banks are referenced as BANK 0, BANK 1, and BANK
2 (see Figure 3-2).
MICLD loads a microprogram into the Extended wcs
one bank at a time.
That is, it breaks each microword into three
32-bit pieces and then loads the pieces consecutively into BANK 0, 1,
and 2.
Two VAX 11/780 Processor Specific registers support the WCS, namely:
the WCS Address Register (WCSA) and the WCS Data Register (WCSD).
The WCSA register consists of 32 bits. The first 16 bits are not
used;
the last 16 bits are divided into three fields.
The WCS
ADDRESS field, occupying bits O through 12, points to the current WCS
address being loaded. The BANK SELECT field (CTR), occupying bits 14
and 13, contains a value of 1, or 2 representing the current bank
being loaded.
The PIN field, occupying bit 15, is set to 1 if any
writes are done with inverted parity. MICLD sets the PIN field to O.
The WCSA register is identified in VAX as processor register number
44.

The WCSD register consists of 32 bits and contains the microcode or
data to be loaded into the WCS.
The WCSD register is identified in
VAX as processor register number 45.
Information is written into and read
from these two VAX processor
registers using the Move to Processor Register (MTPR) and Move from
Processor Register (MFPR)
privileged
instructions provided by the
VAX-11 system.
To load the user WCS, MICLD must first initialize the WCSA register
with the WCS address where the loader is to begin loading microcode.
The Bank Select bits are set to 00.
Several actions take place to
load a complete microword into the WCS.

Step 3:

MICLD loads the second 32 bits of the microword
(destined for BANK 1) into the WCSD register.

Step 4:

VAX repeats Step 2, placing data in BANK 1 at the same
WCS location and auto increments the BANK SELECT field
for BANK 2.

Step 5:

MICLD loads the third 32 bits of the
(destined
for
BANK
2)

completing the WCS load of the microword.

Step 6:

VAX repeats Step 2, placing the data into BANK 2,
resets the BANK SELECT field for BANK O, and increments
the WCS ADDRESS field to point to the next WCS address.

MICLD is then ready to begin loading the next microword into the WCS.

VMS Operating System Support

Programs running under VMS execute in an assigned processor mode.
Listed in ascending order of processor privilege and descending access
capability, there are four processor modes for programs:
1) user,
2)
supervisor,
3)
executive, and 4) kernel. All programs begin at user
mode and may change processor modes depending on the privileges
initially assigned to it.
MICLD begins at user level. MICLD uses the Change Mode to Kernel
command
(CHMK) to elevate itself to kernel mode.
The CHMK command is
documented in the VAX 11/780 Architecture Handbook, Volume 1, Section
13-2.
Successful execution of the CHMK command and other processor mode
commands depends on the program being run in an account equipped with
the necessary privileges.

ERROR MESSAGES

MICLD issues error messages in the VAX standard error message format.
Namely:
%<program-name>-<severity-code>-<abbreviation>,<messa9e>
Where:
is MICLD
is I (information)
E (error)
F (fatal)
<abbreviation> is a short identifier for the message
<message>
is the error message text

CHAPTER 4
EXECUTING A MICROPROGRAM

To execute a microprogram in the extended WCS, the
are necessary:

following

actions

An XFC instruction in a main memory program must be executed.

The field consisting of Bits 1 and O of
System Control Block must be set to 2.

The entry vectory (lOEO hex) must be set to jump to the first
instruction to be executed
in the microprogram in the
Extended WCS.

Vector

the

The following sections describe these actions in detail.

4.1

EXTENDED FUNCTION CALL

A microprogram is invoked by the XFC instruction.
The Extended
Function Call
(XFC)
instruction provides a controlled mechanism for
software to request services of non-standard microcode in the extended
Writeable Control Store
(WCS).
The request is controlled by the
system control block. All opcodes reserved to the extended WCS start
with FC (hex), which is the XFC instruction, using the format:
FC
The XFC instruction has no parameters.
You can pass parameters either as normal operands or
in fixed
registers.
For example, if you have more than one extended function
resident in the WCS, you can use the bytes following
the opcode to
specify which of several extended functions are requested.
Execution of

Page 4-2

Exceptions

The notification of an event relevant primarily to
executing process, which invokes software in the
current process, is termed an exception.

the currently
context of the

Exceptions are handled by, or trapped to, operating system software.
Further, all exceptions either wait for the instruction that caused
them to complete before happening or they restore the processor to the
state it was in prior to E~xecuting the instruction that caused the
execution.
An exception caused by the exE~cution of an XFC instruction (classified
as a fault) occurs during an instruction, leaving the registers and
memory in a consistent state such that elimination of the fault
condition and restarting the instruction will give correct results.
The XFC instruction causes faults called the opcode reserved for
customer and customer reserved exceptions. The value of the PC that
is saved on the stack points to the instruction faulting.
Exceptions are usually reflected to the originating mode as a signal.
In general, the signal is interpreted via a vector in the system
control block.
Separate vectors are defined for each class of
exception and interrupting device controller.

4.1.2

Setting The System Control Block Vector

When an XFC is executed, VMS handles the fault by trapping to vector
14 (hex) of the system control block (SCB) • VMS examines the low
order two bits of the vector and if it finds the value 2, then it
traps to the entry vector (lOEO hex).
The two low order bits of Vector 14 of the SCB must be set to 2 to
execute a microprogram in th«~ Extended WCS. The console data deposit
command can be used to set vector 14 relative to the base SCBB.

4.1.3

Patching The Entry Vector

After vector 14 is accessed, the system traps to address lOEO (hex),
which is resident in the VJ\X microcode area and is called the entry
vector. The entry vector must be loaded with a JUMP microinstruction
to the desired entry point in the extended WCS. This extended WCS
entry point is usually a control routine or exception handler;
however, it can simple be the first instruction in the microcode
function to be performed.

EXECUTING A MICROPROGRAM

Page 4-3

The entry vector is set during the loading process by MICLD if an
/ENTRY file qualifier is given in the MICLD command line. The entry
vector can also be set at the VAX console using the console program.
Note, that when the fault occurs, the ·system traps (in the end) to the
user wcs.
The user defines an exception handler in microcode to
service the "extended customer opcode" fault.
The wcs contains only one application, there is no need for a handler
to resolve what function should be performed in the wcs. However, if
the WCS contain several microroutines, an exception handler must
resolve event by accessing additional data. The microprogrammer must
have a good understanding of the VAX micro machine data path to
develop this exception handler.
More information on the System Control Block and the handling
exceptions can be found in the VAX 11/780 Hardware Handbook.

APPENDIX A
VAX 11/780 FIELD AND MACRO DEFINITIONS

The VAX 11/780 Definition Language identifies the fields of the
microword and provides a macro language to aid you in writing
microprograms.
The sample microprogram in Append ix B is written in
this definition language.
When assembling a program written in this definition language, you
include the definition language source by concatenating your program
file with the definition file VAXDEF.MIC in the MICR02 command line as
follows:
$ MICR02 [SYSLIB]VAXDEF+MYPROG
In the above example, MYPROG.MIC is the name of the file that contains
the source MICR02 microprogram.
The definition language file is available on a floppy in the VAX 11/780
WCS kit.
It is copied to SYS$LIBRARY:VAXDEF.MIC when the kit is
installed on a system.

APPENDIX B
SAMPLE MICROPROGRAM FOR SYSTEM REVISION > 7

This appendix contains a sample VAX 11/780 microprogram, which performs
an unsigned binary search on a vector of longwords in main memory.
The
parameters of the routine, the value to be searched for and the
beginning and end of the vector, are passed in registers.
A command file that assembles, loads, and executes this sample
microprogram is provided in the VAX 11/780 WCS kit.
To invoke this
file in the VMS environment, type:
@[SYSEXE]WCSTOLTST
This command file assembles the input listing
(Section B.l)
and
produces the listing file (Section B.2) and the object file (Section
B.3)
which
are
written
to
[VAXWCSTOL]SAMPLE.MCR
and
[VAXWCSTOL]SAMPLE.ULD.
It then loads the object file into the extended
WCS and runs the test program BSTEST (Appendix D).
BSTEST executes an
XFC instruction, which causes the sample microprogram loaded in the WCS
to be executed.
If the microprogram executes p~operly, BS'l'EST prints
the following message on the terminal:
"Successful Test Completion"

APPENDIX C
SAMPLE MICROPROGRAM FOR SYSTEM REVISION

< 7

This appendix contains a sample VAX 11/780 microprogram, which performs
an unsigned binary search on a vector of longwords in main memory.
The
parameters of the routine, the value to be searched for and the
beginning and end of the vector, are passed in registers.
A command file that assembles, loads, and executes this sample
microprogram is provided in the VAX 11/780 WCS kit.
To invoke this
file in the VMS environment, type:
@[SYSEXE]WCSTOLTST
This command file assembles the input listing
(Section C.l)
and
produces the listing file (Section C.2) and the object file (Section
C.3)
which
are
written
to
[VAXWCSTOL]SAMPLE.MCR
and
[VAXWCSTOL]SAMPLE.ULD.
It then loads the object file into the extended
WCS and runs the test program BSTEST (Appendix D).
BSTEST executes an
XFC instruction, which causes the sample microprogram loaded in the WCS
to be executed.
If the microprogram executes properly, BSTEST pr in ts
the following message on the terminal:
"Successful Test Com pl et ion"
