Section 21 Flash Memory
• Error response H'D0 (1 byte): Error response to 256-byte programming
• ERROR (1 byte): Error code
H'11: Sum-check error
H'2A: Address error (the address is not within the range for the selected MAT)
H'53: Programming error (programming failed because of an error in programming)
Specify H'00 for the lower byte of the address on a boundary corresponding to the unit of
programming (programming size). When less than 256 bytes of data are to be programmed, the
host should transmit the data after padding the vacant bytes with H'FF.
To terminate programming of a given MAT, send a 256-byte programming command with the
address field H'FFFFFFFF. This informs the boot program that all data for the selected MAT have
been sent; the boot program then waits for the next programming/erasure selection command.
Command H'50
Address for programming
SUM
• Command H'50 (1 byte): 256-byte programming
• Address for programming (4 bytes): Terminating code (H'FF, H'FF, H'FF, H'FF)
• SUM (1 byte): Checksum
Response
H'06
• Response H'06 (1 byte): Response to 256-byte programming
This ACK code is returned on completion of the requested programming.
Error
response
H'D0
ERROR
• Error response H'D0 (1 byte): Error response to 256-byte programming
• ERROR (1 byte): Error code
H'11: Sum-check error
H'53: Programming error
