Error
Response
• Error response: H'C8 (1 byte): Error response to erasing selection
• ERROR: (1 byte): Error code
(2) Block Erasure
The boot program will erase the contents of the specified block.
Command
• Command, H'58, (1 byte): Erasure
• Size (1 byte): The number of bytes that represents the erasure block number
• Block Number (1 byte): Number of the block to be erased
• SUM (1 byte): Checksum
Response
• Response, H'06, (1 byte): Response to Erasure
Error
Response
• Error Response, H'D8, (1 byte): Error code
• ERROR: (1 byte): Error code
On receiving block number H'FF, the boot program will stop erasure and wait for a selection
command.
Command
• Command, H'58, (1 byte): Erasure
• Size, (1 byte): The number of bytes that represents the block number
This is fixed to 1.
After erasure has been completed, the boot program will return ACK.
This is fixed to 1.
H'54: Selection processing error (transfer error occurs and processing is not completed)
H'11: Sum check error
H'29: Block number error
H'51: Erasure error
