Figure 10-11 shows an example of the operation when receiving in asynchronous mode.
3. Operation in Synchronous Mode
In synchronous mode, SCI3 transmits and receives data in synchronization with clock pulses. This
mode is suitable for high-speed serial communication.
SCI3 has separate transmission and reception units, allowing full-duplex communication with a
shared clock.
As the transmission and reception units are both double-buffered, data can be written during
transmission and read during reception, making possible continuous transmission and reception.
