 Block Number (1 byte) : Number of the block to be erased
 SUM (1 byte) : Checksum
Response H'06
 Response, H'06, (1 byte) : Response to Erasure
After erasure has been completed, the boot program will return ACK.
Error
response H'D8
ERROR
 Error Response, H'D8, (1 byte) : Error code
 ERROR (1 byte) : Error code
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, (1 byte) : Erasure
 Size (1 byte) : The number of bytes that represents the block number
This is fixed to 1.
 Block Number (1 byte) : H'FF
Stop code for erasure
 SUM (1 byte) : Checksum
Response H'06
 Response, H'06, (1 byte) : Response to end of erasure (ACK)
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.
• Memory read
The boot program will return the data in the specified address.
Command H'52
Size
Area
Read address
Read size
SUM
 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)
