5.10.7 MICROWIRE/PLUS ISP
TI Semiconductor provides a program, which is available from our web site at www.ti.com, that is capable
of programming a device from the parallel port of a PC. The software accepts manually input commands
and is capable of downloading standard Intel HEX Format files.
Users who wish to write their own MICROWIRE/PLUS ISP host software should refer to the COP8 FLASH
ISP User Manual, available from the same web site. This document includes details of command format
and delays necessary between command bytes.
The MICROWIRE/PLUS ISP supports the following features and commands:
Write a value to the ISP Write Timing Register. NOTE: This must be the first command after entering
MICROWIRE/PLUS ISP mode.
Erase the entire flash program memory (mass erase).
Erase a page at a specified address.
Read Option register.
Read a byte from a specified address.
Write a byte to a specified address.
Read multiple bytes starting at a specified address.
Write multiple bytes starting at a specified address.
Exit ISP and return execution to flash program memory.
The following table lists the MICROWIRE/PLUS ISP commands and provides information on required
parameters and return values.

5.10.8 USER ISP AND VIRTUAL E
2
The following commands will support transferring blocks of data from RAM to flash program memory, and
vice-versa. The user is expected to enforce application security in this case.
Erase the entire flash program memory (mass erase). NOTE: Execution of this command will force the
device into the MICROWIRE/PLUS ISP mode.
