14.4.6
This module can be operated with the clocked synchronous serial format, by setting the FS bit in
SAR to 1. When the MST bit in ICCR1 is 1, the transfer clock output from SCL is selected. When
MST is 0, the external clock input is selected.
Data Transfer Format: Figure 14.13 shows the clocked synchronous serial transfer format.
The transfer data is output from the rise to the fall of the SCL clock, and the data at the rising edge
of the SCL clock is guaranteed. The MLS bit in ICMR sets the order of data transfer, in either the
MSB first or LSB first. The output level of SDA can be changed during the transfer wait, by the
SDAO bit in ICCR2.
Transmit Operation: In transmit mode, transmit data is output from SDA, in synchronization
with the fall of the transfer clock. The transfer clock is output when MST in ICCR1 is 1, and is
