22.8 Operation Commands
TMP89FM42
RA002
4. RAM loader command
The RAM loader transfers the Intel Hex format data sent by the external controller to the built-in RAM.
If it completes the data transfer normally, it calculates the checksums, transmits the calculation results,
jumps to the RAM address specified by the first data record, and starts to execute the user program. If the
security program is enabled, the RAM loader command is not executed. In this case, execute Chip Erase
beforehand by using the flash memory erase command. Before executing the RAM loader command, the
TMP89FM42 performs password authentication except where a product is blank. If a password is not
authenticated, the RAM loader command is not executed.
5. Flash memory SUM output command
Checksums in the entire flash memory area (0x8000 through 0xFFFF) are calculated, and the calcula-
tion results are returned.
6. Product ID code output code
This is a code output used to identify a product. The output code consists of information on the ROM
area and on the RAM area respectively. The external controller reads this code to identify the product to
which data is to be written.
7. Flash memory status output code
The status of 0xFFE0 through 0xFFFF and that of the security program are output. The external control-
ler reads this code to identify the status of flash memory.
8. Mask ROM emulation setting command
9. Flash memory security setting command
This command is used to prohibit the reading or writing of data in flash memory in parallel mode. In
serial PROM mode, the flash memory write command and RAM loader command are prohibited. To dis-
able the flash memory security program, execute Chip Erase by using the flash memory erase command.
This command is nonfunctional in the TMP89FM42. It becomes functional if used for a product with
flash memory of more than 96Kbytes.
