128-Byte Programming

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

program the user boot MATs or 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.

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.
