Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
bit RE in the SCI1 SCR, and bit P33DDR.
Note: * When P33ODR = 1, the pin becomes an NMOS open-drain output.
The pin function is switched as shown below according to the combination of
bit RE in the SCI0 SCR, and bit P32DDR.
Note: * When P32ODR = 1, the pin becomes an NMOS open-drain output.
The pin function is switched as shown below according to the combination of
bit TE in the SCI1 SCR, and bit P31DDR.
Note: * When P31ODR = 1, the pin becomes an NMOS open-drain output.
The pin function is switched as shown below according to the combination of
bit TE in the SCI0 SCR, and bit P30DDR.
Note: * When P30ODR = 1, the pin becomes an NMOS open-drain output.
