ï£§ Programming address (four bytes): Start address for programming

Multiple of the size specified in response to the programming unit inquiry; a 128-byte

boundary (e.g. H'00, H'01, H'00, H'00: H'01000000)

ï£§ Data (n bytes): Data to be programmed

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

ï£§ SUM (one byte): Checksum

Response H'06

ï£§ Response: H'06 (one byte): Response to 128-byte programming

On completion of programming, the boot program will return ACK. In two-MAT

programming, when all data for the first MAT has been received, the boot program will

return ACK.

Error response H'D0 ERROR

ï£§ Error response: H'D0 (one byte): Error response to 128-byte programming

ï£§ ERROR: (one byte): Error code

H'11: Sum check error

H'2A: Address error (address is not within the specified range)

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 byte 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.

In two-user-MAT simultaneous programming, the host should alternately send the data for

each MAT address.

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 programming and

wait for selection of programming or erasing. When the most recently received data has not

been programmed in two-user-MAT simultaneous programming, the most recent data is

programmed before programming is stopped.

Command H'50 Programming SUM

address

ï£§ Command: H'50 (one byte): 128-byte programming

ï£§ Programming address (four bytes): End code is H'FF, H'FF, H'FF, H'FF.

ï£§ SUM (one byte): Checksum

Error response H'D0 ERROR

ï£§ Error response: H'D0 (one byte): Error response to 128-byte programming
