PDM70 programmable data mover pocket reference

This document serves as a pocket reference for the digital PDM70 programmable data mover, providing comprehensive technical details for its operation and configuration. It outlines various clock rates and their corresponding baud rates for different system and clock signals (SYS CLK, CLK 1, CLK 2, CLK 3).

The reference includes a modified ASCII code chart and a control character conversion chart mapping PDM70 octal codes to ASCII mnemonics and TTY keyboard commands. It details various command types:

• General Address Commands: For alerting source and destination addresses.
• Programming Commands: For entering and leaving programming mode.
• Data Transfer Commands: For initiating, transferring literals, and ending data transfers.
• Miscellaneous Commands: For single program pass, source mode, and time delay.

A general programming protocol is presented with examples and a legend explaining the syntax. The document also describes different PDM70 hardware configurations (e.g., AA, AB, BA, BB, CA, CB) based on power requirements, display options, and I/O capabilities, along with specific control options (programmable bus control, PROM read-in, bit serial bus interface) and various I/O options (digital I/O, analog I/O, bit serial I/O, parallel I/O). Accessories for the PDM70 are listed, and the general serial word format (7-bit, even parity, one start bit, one stop bit) is specified.

Finally, it explains the data response mechanisms from PDM70 source options, detailing how data is transmitted based on internal/external synchronization, and provides comprehensive data formats for PDM70 destination options, specifying mode characters, BCD digit formats (MSD/LSD), and termination requirements.
