Figure 26.7 shows an Example of Synchronous Serial Communication Unit Operation during Data Reception
(Clock Synchronous Communication Mode, 8-Bit SSU Data Transfer Length). During data reception, the
synchronous serial communication unit operates as described below (the data transfer length can be set from 8
to 16 bits using the SSBR register).
When the synchronous serial communication unit is set as the master device, it outputs a synchronous clock and
inputs data. When the synchronous serial communication unit is set as a slave device, it inputs data
synchronized with the input clock.
When the synchronous serial communication unit is set as the master device, it outputs a receive clock and
starts receiving by performing dummy read from the SSRDR register.
After 8 bits of data are received, the RDRF bit in the SSSR register is set to 1 (data in the SSRDR register) and
receive data is stored in the SSRDR register. When the RIE bit in the SSER register is set to 1 (RXI and OEI
interrupt requests enabled) at this time, an RXI interrupt request is generated. If the SSDR register is read, the
RDRF bit is automatically set to 0 (no data in the SSRDR register).
Read the receive data after setting the RSSTP bit in the SSCRH register to 1 (receive operation is completed
after receiving 1 byte of data). The synchronous serial communication unit outputs a clock for receiving 8 bits
of data and stops. After that, set the RE bit in the SSER register to 0 (reception disabled) and the RSSTP bit to 0
(receive operation is continued after receiving the 1 byte of data) and read the receive data. If the SSRDR
register is read while the RE bit is set to 1 (reception enabled), a receive clock is output again.
When the 8th clock rises while the RDRF bit is set to 1, the ORER bit in the SSSR register is set to 1 (overrun
error: OEI) and the operation is stopped. When the ORER bit is set to 1, reception cannot be performed.
Confirm that the ORER bit is set to 0 before restarting reception.
Figure 26.8 shows a Sample Flowchart of Data Reception (MSS = 1) (Clock Synchronous Communication
Mode).
