15.4.3
In clocked synchronous mode, the SCIF transmits and receives data in synchronization with clock
pulses. This mode is suitable for high-speed serial communication.
The SCIF transmitter and receiver are independent, so full-duplex communication is possible
while sharing the same clock. The transmitter and receiver are also 16-byte FIFO buffered, so
continuous transmitting or receiving is possible by reading or writing data while transmitting or
receiving is in progress.
Figure 15.9 shows the general format in clocked synchronous serial communication.
