• Manufacturer Part Number: h8s-2172
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family H8s-2100 Series
• Manufacturer: Renesas Electronics Corporation.

• Programming Address (four bytes): Start address for programming
• Programming Data (128 bytes): Data to be programmed
• SUM (one byte): Checksum
• Response, H'06, (one byte): Response to 128-byte programming
• Error response, H'D0, (one byte): Error response for 128-byte programming
• ERROR: (one byte): Error code
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, (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, (one byte): Response to 128-byte programming

Error Response
Command
Response
Multiple of the size specified in response to the programming unit inquiry
(i.e. H'00, H'01, H'00, H'00 : H'01000000)
The size is specified in the response to the programming unit inquiry.
On completion of programming, the boot program will return ACK.
On completion of programming, the boot program will return ACK.
