Command
Response
Error
response
⎯ ERROR (1 byte): Error code
⎯ Command H'50 (1 byte): 128-byte programming
⎯ Address for programming (4 bytes): Address where programming starts
⎯ Programming data (n bytes): Data for programming
⎯ SUM (1 byte): Checksum
⎯ Response H'06 (1 byte): Response to 128-byte programming
⎯ Error response H'D0 (1 byte): Error response to 128-byte programming
⎯ ERROR (1 byte): Error code
128-byte programming
H'54: Error in selection processing (processing was not completed because of a transfer
error)
Specify an address on a 128-byte boundary.
[Example] H'00, H01, H'00, H'00: H'00010000
The length of the programming data is the size returned in response to the programming
size inquiry command.
The ACK code is returned on completion of the requested programming.
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)
