• Size (1 byte): The number of bytes that represents the erasure block number
This is fixed to 1.
• Block number (1 byte): Number of the block to be erased
• SUM (1 byte): Checksum
Response H'06
• Response, H'06, (1 byte): Response to Erasure
After erasure has been completed, the boot program will return ACK.
Error Response H'D8 ERROR
• Error Response, H'D8, (1 byte): Response to Erasure
• ERROR (1 byte): Error code
H'11:
H'29:
H'51:
