Command Data
The eight commands shown in Table 19-6 are used in the serial PROM mode. After reset release, the

execute the user program. When the read protection is enabled, the RAM loader mode is not activated. In

Writes to the specified RAM area (address 0040H to 10BFH).
Outputs the 2-byte checksum upper byte and lower byte in this order for the
entire area of the flash memory (address 4000H to 07EFFH, and FFF00 to
FFFFFH).
Outputs the product ID code (13-byte data).
Outputs the status code (7-byte data) such as the read protection condition.
Enables the read protection.
