17.3.4
In the clock synchronous mode, the SCI transmits and receives data in synchronization with clock
pulses. This mode is suitable for high-speed serial communication.
The SCI transmitter and receiver are independent, so full-duplex communication is possible while
sharing the same clock. The transmitter and receiver are also double buffered, so continuous
transmitting or receiving is possible by reading or writing data while transmitting or receiving is in
progress.
Figure 17.17 shows the general format in clock synchronous serial communication.
In clock synchronous serial communication, each data bit is output on the communication line
from one falling edge of the serial clock to the next. Data are guaranteed valid at the rising edge of
the serial clock.
In each character, the serial data bits are transmitted in order from the LSB (first) to the MSB
(last). After output of the MSB, the communication line remains in the state of the MSB.
In the clock synchronous mode, the SCI transmits or receives data by synchronizing with the
rising edge of the serial clock.
