Figure 18.27 Programming Sequence
(1) User boot MAT programming selection
The boot program will transfer a programming program. The data is programmed to the user boot
MATs by the transferred programming program.
Command H'42
 Command, H'42, (1 byte) : User boot-program programming selection
Response H'06
 Response, H'06, (1 byte) : Response to user boot-program programming selection
When the programming program has been transferred, the boot program will return ACK.
Error
response H'C2
ERROR
 Error response : H'C2 (1 byte): Error response to user boot MAT programming selection
 ERROR : (1 byte): Error code
H'54 : Selection processing error (transfer error occurs and processing is not completed)
(2) User MAT programming selection.
The boot program will transfer a programming program. The data is programmed to the user
MATs by the transferred programming program.
