Selection of transfer format
In clock synchronous serial communication, transfer format can be
selected by bit 7 of the transmit/receive control register 0. When bit 7
is
0
, transfer format is LSB first. When bit 7 is
1
, transfer format is
MSB first.
This function is realized by changing connection relation between
the transmit buffer register and the receive buffer register when writ-
ing transmit data to the transmit buffer register or reading receive
data from the receive buffer register. Accordingly, the transmitter
s
operation is the same in both transfer formats.
Figure 68 shows the connection relation.

Precautions for clock synchronous serial
communication
In the clock synchronous serial communication, the separate func-
tion for CTS
i
/RTS
i
cannot be selected. Furthermore, when an inter-
nal clock is selected, RTS output is undefined. Therefore, do not use
the RTS function.
Before transmit operation is performed, be sure to clear bits 2, 3 and
5 of the serial I/O pin control register (address AC
16
) to
00
.
