The following are examples in which functions (a) to (e) are chosen:

_______

• Transmission WITH: CTS function, WITHOUT: other functions .............................................. P2-84

_______

• Reception WITH: RTS function, WITHOUT: other functions ................................................... P2-88

Also, the SIM interface is used by adding some extra settings in UART2's clock-asynchronous serial

I/O mode. Direct or inverse format is selected by connecting SIM card.

• Transmission WITH: direct format ........................................................................................... P2-92

• Reception WITH: direct format ................................................................................................ P2-96

(6) Input to the serial I/O and the direction register

To input an external signal to the serial I/O, set the direction register of the relevant port to input.

(7) Pins related to the serial I/O

_________

_________ __________

• CTS0, CTS1, CTS2 pins

_______

:Input pins for the CTS function

_________

• RTS0, RTS1, RTS2 pins

_______

:Output pins for the RTS function

• CLK0, CLK1 pins

:Input pins for the transfer clock

• RxD0, RxD1, RxD2 pins

:Input pins for data

• TxD0, TxD1, TxD2 pins

:Output pins for data

Since TxD2 pin is N-channel open drain, this pin needs pull-up resistor.
