After adjustment of the bit rate, the protocol for communications between the host and the boot
program is as shown below.
(1) One-byte commands and one-byte responses
(2) n-byte commands or n-byte responses
(3) Error response
(4) Programming of 128 bytes
(5) Memory read response
Rev. 2.0, 06/04, page 648 of 980
Communications Protocol
These commands and responses are comprised of a single byte. These are consists of the
inquiries and the ACK for successful completion.
These commands and responses are comprised of n bytes of data. These are selections and
responses to inquiries.
The amount of programming data is not included under this heading because it is determined
in another command.
The error response is a response to inquiries. It consists of an error response and an error code
and comes two bytes.
The size is not specified in commands. The size of n is indicated in response to the
programming unit inquiry.
This response consists of four bytes of data.
