Response H'06
 Response: H'06 (one byte): Response to erasing selection
After the erasing program has been transferred, the boot program will return ACK.
Error response H'C8 ERROR
 Error response: H'C8 (one byte): Error response to erasing selection
 ERROR: (one byte): Error code
H'54: Selection processing error (transfer error occurs and processing is not completed)
(2) Block erasing
The boot program will erase the contents of the specified block.
Command H'58 Size Block number SUM
 Command: H'58 (one byte): Erasing
 Size (one byte): Number of characters that represents the erasure block number (fixed at 1)
 Block number (one byte): Number of the block whose data is to be erased
 SUM (one byte): Checksum
Response H'06
 Response: H'06 (one byte): Response to erasing
After erasure has been completed, the boot program will return ACK.
Error response H'D8 ERROR
 Error response: H'D8 (one byte): Error response to erasing
H'11: Sum check error
H'29: Block number error
Block number is incorrect.
H'51: Erasure error
An error has occurred during erasure.
On receiving block number H'FF, the boot program will stop erasure and wait for a
selection command.
Command H'58 Size Block number SUM
 Command: H'58 (one byte): Erasure
 Size (one byte): Number of characters that represents the block number (fixed at 1)
 Block number (one byte): H'FF (stop code for erasure)
 SUM (one byte): Checksum
Response H'06
 Response: H'06 (one byte): Response to end of erasure (ACK)
When erasure is to be performed again after the block number H'FF has been sent, the
procedure should be executed from the erasure selection command.
(3) Memory read
The boot program will return the data in the specified address.
