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 writing
transmit data to the transmit buffer register or reading receive data
from the receive buffer register. Accordingly, the transmitter’s opera-
tion is the same in both transfer formats.
Figure 64 shows the connection relation.
