Section 21 Flash Memory
(a)
The boot program will transfer the erasure program. User ROM data is erased by the transferred
erasure program.
• Command, H'48, (1 byte): Erasure selection
• Response, H'06, (1 byte): Response for erasure selection
• Error response, H'C8, (1 byte): Response to erasure selection
• ERROR (1 byte): Error code
(b) Block Erasure
The boot program will erase the contents of the specified block.
• Command, H'58, (1 byte): Block 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, H'06, (1 byte): Response to Erasure
• Error response, H'D8, (1 byte): Response to block erasure
• ERROR (1 byte): Error code

Error response
After the erasure program has been transferred, the boot program will return ACK.
H'54: Selection processing error (transfer error occurs and processing is not completed)
This is fixed to 1.
After erasure has been completed, the boot program will return ACK.
H'11: Sum check error
H'29: Block number error
H'51: Erasure error
Erasure Selection
Block number is incorrect.
An error has occurred during erasure.
