13.1.3
This LSI includes 1 channel of UART (Universal Asynchronous Receiver Transmitter) which is an asynchrnous serial
interface.
For the input clock, see Chapter 6, “Clock Generation Circuit”.
The use of UART requires setting of the secondary functions of Port 4. For setting of the secondary functions of Port
4, see Chapter 20, “Port 4”.
Figure 13-1 shows the configuration of the UART.
