Refer to 16.2.8.1 Accessing Registers Associated w ith Clock Synchronous Serial I/O w ith Chip Select for
more information.
The SSRDR register retains the data received before an overrun error occurs (ORER bit in the SSSR register set to 1
(overrun error)). When an overrun error occurs, the receive data may contain errors and therefore should be
discarded.

Store the transmit data.
The stored transmit data is transferred to the SSTRSR register and transmission is started
w hen it is detected that the SSTRSR register is empty.
When the next transmit data is w ritten to the SSTDR register during the data transmission from
the SSTRSR register, the data can be transmitted continuously.
When the MLS bit in the SSMR register is set to 1 (transfer data w ith LSB-first), the data in
w hich MSB and LSB are reversed is read, after w riting to the SSTDR register.
Store the receive data.
The receive data is transferred to the SSRDR register and the receive operation is completed
w hen 1 byte of data has been received by the SSTRSR register. At this time, the next receive
operation is possible. Continuous reception is possible using registers SSTRSR and SSRDR.
