SCI Interface Setting by Host: When boot mode is initiated, this LSI measures the low period of
asynchronous SCI-communication data (H'00), which is transmitted consecutively by the host.
The SCI transmit/receive format is set to 8-bit data, 1 stop bit, and no parity. This LSI calculates
the bit rate of transmission by the host by means of the measured low period and transmits the bit
adjustment end sign (1 byte of H'00) to the host. The host must confirm that this bit adjustment
end sign (H'00) has been received normally and transmits 1 byte of H'55 to this LSI. When
reception is not executed normally, boot mode is initiated again (reset) and the operation described
above must be executed. The bit rate between the host and this LSI is not matched by the bit rate
of transmission by the host and system clock frequency of this LSI. To operate the SCI normally,
the transfer bit rate of the host must be set to 4,800 bps, 9,600 bps, or 19,200 bps.
The system clock frequency, which can automatically adjust the transfer bit rate of the host and
the bit rate of this LSI, is shown in table 14.7. Boot mode must be initiated in the range of this
system clock.
