Figure 15.18
When setting the FS bit in the SAR register to “1”, the clock synchronous serial format is used to
communicate. Figure 15.18 shows the Transfer Format of Clock Synchronous Serial Format.
When the MST bit in the ICCR1 register is set to “1”, the transfer clock is output from the SCL pin and
when the MST bit is set to “0”, the external clock is input.
The transfer data is output between the fall and the following fall of the SCL clock, and data is
determined by the rise of the SCL clock. The MSB-first or LSB-first can be selected for the order of the
data transfer by setting the MLS bit in the ICMR register. The SDA output level can be changed by the
SDAO bit in the ICCR2 register during the transfer standby.
