Where the sequence of programming operations that is executed includes programming with
another method or of another MAT, the procedure must be repeated from the programming
selection command.
The sequence for programming-selection and 128-byte programming commands is shown in
figure 17.86.
(2) 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
• Command, H'42, (1 byte): User boot-program programming selection
Response
• Response, H'06, (1 byte): Response to user boot-program programming selection
Error
Response
• Error response: H'C2 (1 byte): Error response to user boot MAT programming selection
• ERROR: (1 byte): Error code
When the programming program has been transferred, the boot program will return ACK.
H'54: Selection processing error (transfer error occurs and processing is not completed)
