Error Response
The specified address should match the unit for programming of data. For example, when the
programming is in 128-byte units, the lower eight bits 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.

Error Response
(10) Erasure
Erasure is performed with the erasure selection and block erasure commands.
Firstly, erasure is selected by the erasure selection command and the boot program then erases the
specified block by a block-erasure command. The block-erasure 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.
• Error response, H'D0, (one byte): Error response for 128-byte programming
