23. Serial Interface (UARTi (i = 0 or 1))
The serial interface consists of three channels, UART0 to UART2. This chapter describes UARTi (i = 0 or 1).
23.1
UART0 and UART 1 have a dedicated timer to generate a transfer clock and operate independently. Clock
synchronous serial I/O mode and clock asynchronous serial I/O mode (UART mode) are supported.
Figure 23.1 shows a Block Diagram of UARTi (i = 0 or 1). Figure 23.2 shows a Block Diagram of UARTi (i = 0 or 1)
Transmit/Receive Unit. Table 23.1 lists the Pin Configuration of UARTi (i = 0 or 1).
