Figure 23.30 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 (one byte): User boot MAT programming selection
Response H'06
 Response: H'06 (one byte): Response to user boot MAT programming selection
When the programming program has been transferred, the boot program will return ACK.
Error response H'C2 ERROR
 Error response: H'C2 (one byte): Error response to user boot MAT programming selection
— ERROR: (one 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.
Command H'43
 Command: H'43 (one byte): User MAT programming selection
