• SUM (one byte): Checksum
• Response, H'06, (one byte): Response to Erasure
• Error Response, H'D8, (one byte): Response to Erasure
• ERROR (one byte): Error code
On receiving block number H'FF, the boot program will stop erasure and wait for a selection
command.
• Command, H'58, (one byte): Erasure
• Size, (one byte): The number of bytes that represents the block number
• Block number (one byte): H'FF
• SUM (one byte): Checksum

After erasure has been completed, the boot program will return ACK.
This is fixed to 1.
Stop code for erasure
When erasure is to be performed after the block number H'FF has been sent, the procedure
should be executed from the erasure selection command.
