TMP89FM42
RA002
22.8.7.1 Flash memory status code
The flash memory status code is 7-byte data. It shows the status of the flash memory security program
and that of the address from 0xFFE0 to 0xFFFF.
Restrictions are placed on the execution of some operation commands, depending on the contents of the
status code 1. Detailed information on this is shown in the table below. If the security program is enabled,
three commands cannot be executed: the flash memory write command, RAM loader mode command,
and Sector Erase command. To execute these commands, Chip Erase must be performed on flash memory
before they are executed.
