19. Serial Interface (UART0)
The serial interface consists of two channels: UART0_0 and UART0_1.
This chapter describes these channels as UART0 unless there are differences among them.

Interrupt sources
Each UART0 channel is independent and has a dedicated timer for generating a transfer clock. It supports two
modes: Clock synchronous serial I/O mode and clock asynchronous serial I/O (UART) mode.
Table 19.1 lists the UART0 Specifications. Figure 19.1 shows the UART0 Block Diagram. Figure 19.2 shows the
Transmit/Receive Unit Block Diagram. Table 19.2 lists the UART0 Pin Configuration.

• The CKDIR bit in the U0MR register is 0 (internal clock): fi/2 (n + 1)
• The CKDIR bit in the U0MR register is 1 (external clock):
• Character bits (transfer data): 7, 8, or 9 bits selectable
• Start bit: 1 bit
• Parity bit: Odd, even, or none selectable
• Stop bit: 1 or 2 bits selectable
• The CKDIR bit in the U0MR register is 0 (internal clock): fj/16 (n + 1)
• The CKDIR bit in the U0MR register is 1 (external clock): fEXT/16 (n + 1)
