(13) User-Boot Program Sum Check
The boot program will return the byte-by-byte total of the contents of the bytes of the user-boot
program, as a four-byte value.
• Command, H'4A, (one byte): Sum check for user-boot program
• Response, H'5A, (one byte): Response to the sum check of user-boot program
• Size (one byte): The number of bytes that represents the checksum
• Checksum of user boot program (four bytes): Checksum of user boot MATs
Response
Error Response
Command
Response
H'00: User boot MAT
H'01: User MAT
H'11: Sum check error
H'2A: Address error
H'2B: Size error
This is fixed to 4.
The total of the data is obtained in byte units.
An address error occurs when the area setting is incorrect.
The read address is not in the MAT.
The read size exceeds the MAT.
