Fig. 33 Serial I/O port block diagram
SERIAL I/O PORTS
Two independent serial I/O ports are provided. Figure 33 shows a
block diagram of the serial I/O ports.
Bits 0, 1, and 2 of the UARTi (i = 0, 1) Transmit/Receive mode reg-
ister shown in Figure 34 are used to determine whether to use port
P8 as parallel port, clock synchronous serial I/O port, or asynchro-
nous (UART) serial I/O port using start and stop bits.
Figures 35 and 36 show the connections of receiver/transmitter
according to the mode.
Figure 37 shows the bit configuration of the UARTi transmit/re-
ceive control register.
Each communication method is described below.
