(b) Block Erasure
The boot program will erase the contents of the specified block.
Command
Response
Error Response
On receiving block number H'FF, the boot program will stop erasure and wait for a selection
command.
Command
Response
When erasure is to be performed after the block number H'FF has been specified, the procedure
should be executed from the erasure selection command.
• Command, H'58, (one byte): Erasure
• Size (one byte): The number of bytes that represents the erasure block number
• Block number (one byte): Number of the block to be erased
• SUM (one byte): Checksum
• Response, H'06, (one byte): Response to erasure
• Error response, H'D8, (one byte): Error response to erasure
• ERROR (one byte): Error code
• 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
• Response, H'06, (one byte): Response to end of erasure (ACK)
This is fixed to 1.
After erasure has been completed, ACK will be returned.
This is fixed to 1.
