Section 22 Flash Memory
(12) User ROM Sum Check
The boot program will add all the data bytes in the user ROM area and return the result in
response to a user ROM sum check command.
• Command, H'4B, (1 byte): Sum check for user ROM
• Response, H'5B, (1 byte): Response to the user ROM sum check
• Size (1 byte): The number of bytes that represents the checksum
• Checksum of user ROM (4 bytes): Result of checksum calculation for the user ROM area; the
• SUM (1 byte): Sum check for data being transmitted
(13) Data Flash Sum Check
The boot program will add all the data bytes in the data flash area and return the result in response
to a data flash sum check command.
• Command, H'61, (1 byte): Sum check for data flash
• Response, H'71, (1 byte): Response to the data flash sum check
• Size (1 byte): The number of bytes that represents the checksum
• Checksum of data flash (4 bytes): Result of checksum calculation for the data flash area; the
• SUM (1 byte): Checksum value that makes the sum of the bytes from the command to the
(14) User ROM Blank Check
The boot program will check to see if the whole user ROM area is blank and return the result in
response to a user ROM blank check command.
• Command, H'4D, (1 byte): Blank check for user ROM
