(1)
The bit rate is calculated by measuring the period of transfer of a low-level byte (H'00) from the
host. The bit rate can be changed by the command for a new bit rate selection. After the bit rate
has been adjusted, the boot program enters the inquiry and selection state. The bit-rate-adjustment
sequence is shown in figure 22.22.
(2)
After adjustment of the bit rate, the protocol for serial 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
These one-byte commands and one-byte responses consist 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 program data size 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.
