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'2A: Address error
H'53: Programming error
An error has occurred in programming and programming cannot be continued.
(10) 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 issuing the erasure selection command and block-erasure command are shown in
figure 19.23.
