Section 21 Flash Memory (0.18-μm F-ZTAT Version)
• Programming Data (128 bytes): Data to be programmed
• SUM (one byte): Checksum
Response
• Response, H'06, (one byte): Response to 128-byte programming
Error Response
• Error response, H'D0, (one byte): Error response for 128-byte programming
• ERROR: (one byte): Error code
The specified address should match the unit for programming of data. For example, when the
programming is in 128-byte units, the lower byte of the address should be H'00 or H'80.
When there are less than 128 bytes of data to be programmed, the host should fill the rest with
H'FF.
Sending the 128-byte programming command with the address of H'FFFFFFFF will stop the
programming operation. The boot program will interpret this as the end of the programming and
wait for selection of programming or erasing.
Command
• Command, H'50, (one byte): 128-byte programming

• SUM (one byte): Checksum
Response
• Response, H'06, (one byte): Response to 128-byte programming
Error Response
• Error Response, H'D0, (one byte): Error response for 128-byte programming
