Selection Method and Pin Functions

3/RxD1

The pin function is switched as shown below according to the combination of

bit RE in the SCI1 SCR, and bit P33DDR.

P33DDR

—

Pin function

3 input pin

3 output pin*

RxD1 input pin

Note:

When P33ODR = 1, the pin becomes an NMOS open drain output.

2/RxD0

The pin function is switched as shown below according to the combination of

bit RE in the SCI0 SCR, and bit P32DDR.

P32DDR

—

Pin function

2 input pin

2 output pin*

RxD0 input pin

Note:

When P32ODR = 1, the pin becomes an NMOS open drain output.

1/TxD1

The pin function is switched as shown below according to the combination of

bit TE in the SCI1 SCR, and bit P31DDR.

P31DDR

—

Pin function

1 input pin

1 output pin*

TxD1 output pin*

Note:

When P31ODR = 1, the pin becomes an NMOS open drain output.
