(g)
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
• Command, H'4A, (one byte): Sum check for user-boot program
Response
• 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
• SUM (one byte): Sum check for data being transmitted
(h) User MAT 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, (one byte): Sum check for user program
Response
• Response, H'5B, (one byte): Response to the sum check of the user program
