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.
Command
• Command, H'4A, (1 byte): Sum check for user-boot program
Response
• Response, H'5A, (1 byte): Response to the sum check of user-boot program
• Size (1 byte): The number of bytes that represents the checksum
• Checksum of user boot program (4 bytes): Checksum of user boot MATs
• SUM (1 byte): Sum check for data being transmitted
User-Program Sum Check
The boot program will return the byte-by-byte total of the contents of the bytes of the user
program.
Command
• Command, H'4B, (1 byte): Sum check for user program
Response
• Response, H'5B, (1 byte): Response to the sum check of the user program
• Size (1 byte): The number of bytes that represents the checksum
• Checksum of user boot program (4 bytes): Checksum of user MATs
• SUM (1 byte): Sum check for data being transmitted
This is fixed to 4.
The total of the data is obtained in byte units.
