UARTi (i = 0 to 2) 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 03A0
serial I/O or as a UART. Although a few functions are different, UART0 and UART1 have almost the
same functions.
UART0 through UART2 are almost equal in their functions with minor exceptions.Table 1.23 shows the
comparison of functions of UART0 through UART2, and Figure 1.77, Figure 1.78, Figure 1.79, Figure
1.80, and Figure 1.81 show the registers related to UARTi.
