• 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
