• P32/RxD0/IrRxD
The pin function is switched as shown below according to the combination of bit RE in SCR of
SCI_0 and bit P32DDR.
RE 0 1
P32DDR 0 1 —
Pin function P32 input P32 output
*
RxD0/IrRxD
input
Note: * NMOS open-drain output when P32ODR = 1.
• P31/TxD1
The pin function is switched as shown below according to the combination of bit TE in SCR of
SCI_1 and bit P31DDR.
TE 0 1
P31DDR 0 1 —
Pin function P31 input P31 output
*
TxD1 output
*
Note: * NMOS open-drain output when P31ODR = 1.
• P30/TxD0/IrTxD
The pin function is switched as shown below according to the combination of bit TE in SCR of
SCI_0 and bit P30DDR.
TE 0 1
P30DDR 0 1 —
Pin function P30 input P30 output
*
RxD0/IrRxD
output
