15. Serial Interface
The serial interface consists of two channels (UART0 and UART1). Each UARTi (i = 0 or 1) has an exclusive timer to
generate the transfer clock and operates independently.
Figure 15.1 shows a UARTi (i = 0 or 1) Block Diagram. Figure 15.2 shows a UARTi Transmit/Receive Unit.
UARTi has two modes: clock synchronous serial I/O mode and clock asynchronous serial I/O mode (UART mode).
Figures 15.3 to 15.7 show the registers associated with UARTi.
