Error Response H'D2 ERROR
• Error response: H'D2 (1 byte): Error response to memory read
• ERROR: (1 byte): Error code
H'11: Sum check error
H'2A: Address error
The read address is not in the MAT.
H'2B: Size error
The read size exceeds the MAT.
(12) User Boot MAT Sum Check
The boot program will return the byte-by-byte total of the contents of the bytes of the user boot
MAT, as a 4-byte value.
Command H'4A
• Command, H'4A, (1 byte): Sum check for user-boot MAT
Response H'5A Size Checksum of user boot program SUM
• Response, H'5A, (1 byte): Response to the sum check of user-boot MAT
• Size (1 byte): The number of bytes that represents the checksum
This is fixed to 4.
• Checksum of user boot program (4 bytes): Checksum of user boot MATs
The total of the data is obtained in byte units.
• SUM (1 byte): Sum check for data being transmitted
(13) User MAT Sum Check

• Command, H'4B, (1 byte): Sum check for user MAT
Response H'5B Size Checksum of user program SUM
• Response, H'5B, (1 byte): Response to the sum check of the user MAT
• Size (1 byte): The number of bytes that represents the checksum
This is fixed to 4.
• Checksum of user boot program (4 bytes): Checksum of user MATs
