H'53 : Programming error
A programming error has occurred and programming cannot be
continued.
The specified address should match the unit for programming of data. For example, when the
programming is in 128-byte units, the lower byte of the address should be H'00 or H'80.
When there are less than 128 bytes of data to be programmed, the host should fill the rest with
H'FF.
Sending the 128-byte programming command with the address of H'FFFFFFFF will stop the
programming operation. The boot program will interpret this as the end of the programming and
wait for selection of programming or erasing.
Command H'50
Address
 Command, H'50, (1 byte) : 128-byte programming
 Programming Address (4 bytes) : End code is H'FF, H'FF, H'FF, H'FF.
 SUM (1 byte) : Checksum
SUM
Response H'06
 Response: H'06 (1 byte): Response to 128-byte programming
On completion of programming, the boot program will return ACK.
Error
response H'D0
ERROR
 Error Response, H'D0, (1 byte) : Error response for 128-byte programming
 ERROR : (1 byte) : Error code
H'11 : Checksum error
H'53 : Programming error
An error has occurred in programming and programming cannot be
continued.
• Erasure
Erasure is performed with the erasure selection and block erasure command.
Firstly, erasure is selected by the erasure selection command and the boot program then erases the
specified block. The command should be repeatedly executed if two or more blocks are to be
erased. Sending a block-erasure command from the host with the block number H'FF will stop the
erasure operating. On completion of erasing, the boot program will wait for selection of
programming or erasing.
The sequences of the issuing of erasure selection commands and the erasure of data are shown in
figure 18.28.
