H'D8

ERROR

• Error response H'D8 (1 byte): Error response to the block erasure command

• ERROR (1 byte): Error code

H'11: Sum-check error

H'29: Block number error (the specified block number is incorrect.)

On receiving the command with H'FF as the block number, the boot program stops erasure

processing and waits for the next programming/erasure selection command.

Command

H'58

Size

Block number

SUM

• Command H'58 (1 byte): Erasure of a block

• Size (1 byte): The number of characters in the block number field (fixed at 1)

• Block number (1 byte): H'FF (erasure terminating code)

• SUM (1 byte): Checksum

Response

H'06

• Response H'06 (1 byte): ACK code to indicate response to the request for termination of

erasure

To perform erasure again after having issued the command with the block number specified as
