Error Response

H'D0

ERROR

• Error response, H'D0, (one byte): Error response for 128-byte programming

• ERROR: (one byte): Error code

H'11: Checksum Error

H'2A: Address error

The address is not in the specified MAT.

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 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.

Command

H'50

Address

SUM

• Command, H'50, (one byte): 128-byte programming

• Programming Address (four bytes): End code is H'FF, H'FF, H'FF, H'FF.

• SUM (one byte): Checksum

Response

H'06

• Response, H'06, (one 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, (one byte): Error response for 128-byte programming

• ERROR: (one byte): Error code

H'11: Checksum error

H'53: Programming error

An error has occurred in programming and programming cannot be continued.
