selection
Serial I/O is configured as five channels: UART0 to UART4.
UART0 to UART4 each have an exclusive timer to generate a transfer clock, so they operate independently
of each other.
Figures 16.1 and 16.2 show the block diagram of UARTi (i=0 to 4). Figures 16.3 and 16.4 show the block
diagram of the transmit/receive unit.
UARTi has two operation modes: a clock synchronous serial I/O mode and a clock asynchronous serial I/O
mode (UART mode). The contents of the serial I/O mode select bits (bits 0 to 2 at addresses 0360
0368
as a UART.
Although a few functions are different, UART0 to UART4 have almost the same functions.
UART2 to UART4, in particular, are compliant with the SIM interface with some extra settings added in
clock-asynchronous serial I/O mode (Note). It also has the bus collision detection function that generates
an interrupt request if the TxD pin and the RxD pin are different in level.
Table 16.1 shows the comparison of functions of UART0 to UART4, and Figures 16.5 through 16.11 show
the registers related to UARTi.
