Serial I/O mode select bits
0 0 0 : Serial I/O is invalid. (Port P1 functions as a programmable I/O port.)
0 0 1 : Clock synchronous
1 0 0 : 7-bit UART
1 0 1 : 8-bit UART
1 1 0 : 9-bit UART
Internal/External clock select bit
0 : Internal clock
1 : External clock
Stop bit length select bit (Valid in UART mode.)
0 : 1 stop bit
1 : 2 stop bits
Odd/Even parity select bit (Valid in UART mode with the parity enable bit = “1”.) (Note)
0 : Odd parity
1 : Even parity
Parity enable bit (Valid in UART mode) (Note)
0 : No parity
1 : With parity
Sleep select bit (Valid in UART mode) (Note)

Note: In the clock synchronous serial I/O mode, bits 4 to 6 are invalid. (Each of them may be “0” or “1”.) Furthermore, fix bit 7 to “0”.
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 through 2 of the UARTi(i = 0, 1) transmit/receive mode register
shown in Figure 55 are used to determine whether to use port P1 as
a programmable I/O port, clock synchronous serial I/O port, or asyn-
chronous (UART) serial I/O port which uses start and stop bits.
Figures 56 and 57 show the block diagrams of the receiver/transmit-
ter.
Figure 58 shows the bit configuration of the UARTi transmit/receive
control register.
Each communication method is described below.
