Command Data
The eight commands shown in Table 19-6 are used in the serial PROM mode. After reset release, the
The serial PROM mode has seven types of modes, that are (1) Flash memory erasing, (2) Flash memory writing,

Erases the flash memory area (address C000H to FFFFH).
Writes to the flash memory area (address C000H to FFFFH).
Writes to the specified RAM area (address 0050H to 023FH).
Outputs the 2-byte checksum upper byte and lower byte in this order for the

Outputs the product ID code (13-byte data).
Outputs the status code (7-byte data) such as the security program condition.
Enables the security program.
