Response
• Response, H'5A, (one byte): Response to the sum check of user boot MAT
• Size (one byte): The number of bytes that represents the checksum
• Checksum of MATs (four bytes): Checksum of user boot MATs
• SUM (one byte): Sum check for data being transmitted
(13) User MAT Sum Check
The boot program will return the byte-by-byte total of the contents of the bytes of the user MAT,
as a four-byte value.
Command
• Command, H'4B, (one byte): Sum check for user MAT
Response
• Response, H'5B, (one byte): Response to the sum check of the user MAT
• Size (one byte): The number of bytes that represents the checksum
• Checksum of MATs (four bytes): Checksum of user MATs
• SUM (one byte): Sum check for data being transmitted
(14) User Boot MAT Blank Check
The boot program will check whether or not all user boot MATs are blank and return the result.
Command
• Command, H'4C, (one byte): Blank check for user boot MAT
Response
• Response, H'06, (one byte): Response to the blank check of user boot MAT
Error Response
• Error response, H'CC, (one byte): Error response to blank check for user boot MAT
• Error code, H'52, (one byte): Erasure has not been completed.
This is fixed to 4.
The total of the data is obtained in byte units.
This is fixed to 4.
The total of the data is obtained in byte units.
If all user boot MATs are blank (H'FF), ACK will be returned.
