SERIAL I/O PORTS
Two independent serial I/O ports are provided. Figure 54 shows a
block diagram of the serial I/O ports.
Bits 0, 1, and 2 of the UARTi(i = 0,1) Transmit/Receive mode register
shown in Figure 55 are used to determine whether to use port P8 as
parallel port, clock synchronous serial I/O port, or asynchronous
(UART) serial I/O port using start and stop bits.
Figures 56 and 57 show the connections of receiver/transmitter ac-
cording to the mode.
Figure 58 shows the bit configuration of the UARTi Transmit/Receive
control register.
Each communication method is described below.
