(a) User MAT Programming Selection

The boot program will transfer a program for user MAT programming selection. The data is

programmed to the user MATs by the transferred program for programming.

Command

H'43

• Command, H'43, (one byte): User-program programming selection

Response

H'06

• Response, H'06, (one byte): Response to user-program programming selection

When the programming program has been transferred, the boot program will return ACK.

Error Response

H'C3

ERROR

• Error response : H'C3 (1 byte): Error response to user-program programming selection

• ERROR : (1 byte): Error code

H'54: Selection processing error (transfer error occurs and processing is not completed)

(b) 128-Byte Programming

The boot program will use the programming program transferred by the programming selection to

program the user MATs in response to 128-byte programming.

Command

H'50

Address

Data

···

SUM

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

• Programming Address (four bytes): Start address for programming

Multiple of the size specified in response to the programming unit inquiry

(i.e. H'00, H'01, H'00, H'00 : H'01000000)

• Program data (128 bytes): Data to be programmed

The size is specified in the response to the programming unit inquiry.

• 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.
