• P84/PWX0
The pin function is switched as shown below according to the combination of the OEA bit in
DACR of the PWMX and the P84DDR bit.

• P83/SDA1/RxD4
The pin function is switched as shown below according to the combination of the RE bit in
SCR of the SCI_4, the ICE bit in ICCRA of the IIC3_1, and the P83DDR bit. When this pin is
used as the P83 output pin, the output format is NMOS push-pull output. The output format for
SDA1 is NMOS open-drain output, and direct bus drive is possible.

• P82/SCL1/TxD4
The pin function is switched as shown below according to the combination of the TE bit in
SCR of the SCI_4, the ICE bit in ICCRA of the IIC3_1, and the P82DDR bit. When this pin is
used as the TxD4 or P82 output pin, the output format is NMOS push-pull output. The output
format for SCL1 is NMOS open-drain output, and direct bus drive is possible.
