Pin Selection Method and Pin Functions
P31/RxD0 Switches as follows according to combinations of SCR RE bit of SCI0 and the
P31DDR bit.
RE 0 1
P31DDR 0 1 —
Pin function P31 input pin P31 output pin
*
RxD0 input pin
Note: * When P31ODR = 1, it becomes NMOS open drain output.
P30/TxD0 Switches as follows according to combinations of SCR TE bit of SCI0 and the
P30DDR bit.
TE 0 1
P30DDR 0 1 —
Pin function P30 input pin P30 output pin
*
TxD0 output pin
*
Note: * When P30ODR = 1, it becomes NMOS open drain output.
