On receiving block number H'FF, the boot program will stop erasure and wait for a selection
command.
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
Response
• Response, H'06, (one byte): Response to end of erasure (ACK)
(e)
The boot program will return the data in the specified address.
Command
• Command: H'52 (1 byte): Memory read
• Size (1 byte): Amount of data that represents the area, read address, and read size (fixed at 9)
• Area (1 byte)
• Read address (4 bytes): Start address to be read from
• Read size (4 bytes): Size of data to be read
• SUM (1 byte): Checksum
Response
• Response: H'52 (1 byte): Response to memory read
• Read size (4 bytes): Size of data to be read
• Data (n bytes): Data for the read size from the read address
• SUM (1 byte): Checksum
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.
H'01: User MAT
Memory Read
An address error occurs when the area setting is incorrect.
