23 Flash Memory Operation
Note that addressing of operation commands is different from the case of standard commands due to the
specific interface arrangements with the CPU. Also note that the flash memory is written in 32-bit blocks. So,
32-bit (word) data transfer commands must be used in writing the flash memory.

23.3.1 Flash Memory
Major functions
In on-board programming, the CPU is to execute software commands for rewriting or erasing the
flash memory. The rewrite/erase control program should be prepared by the user beforehand.
Because the flash memory content cannot be read while it is being written or erased, it is necessary
to run the rewrite/erase program from the internal RAM or from an external memory device after
shifting to the user boot mode.
Except for some functions, writing and erasing flash memory data are in accordance with the
standard JEDEC commands. In writing or erasing, use 32-bit data transfer command of the CPU to
enter commands to the flash memory. Once the command is entered, the actual write or erase
operation is automatically performed internally.

Writes data automatically per page.
Erases the entire area of the flash memory automatically.
Erases a selected block automatically.
By writing a 4-bit protection code, the write or erase function can be individually inhibited for
each block.
