UART0 transmit/receive mode register (address 30 16)

UART1 transmit/receive mode register (address 38 16)

Note: Bits 4 to 6 are ignored in the clock synchronous serial I/O mode. (They may be “0” or “1.”)

Fix bit 7 to “0.”

b2 b1 b0

0: Odd parity

1: Even parity

0: Parity is disabled.

1: Parity is enabled.

0: The sleep mode is terminated. (Ignored.)

8.2.1 UARTi transmit/receive mode register

Figures 8.2.2 and 8.2.3 show the structure of UARTi transmit/receive mode register. The serial I/O mode

selection bits are used to select a UARTi’s operating mode. For bits 4 to 6, refer to section “8.4.2 Transfer

data format.” For bit 7, refer to section “8.4.8 Sleep mode.”
