• P82/SCL1
The pin function is switched as shown below according to the combination of the ICE bit in
ICCR of IIC_1 and the P82DDR bit.
When this pin is used as the P82 output pin, the output format is NMOS push-pull output. The
output format for SCL1 is NMOS open-drain output, which allows direct bus drive.

• P81/SDA0
The pin function is switched as shown below according to the combination of the ICE bit in
ICCR of IIC_0 and the P81DDR bit.
When this pin is used as the P81 output pin, the output format is NMOS push-pull output. The
output format for SDA0 is NMOS open-drain output, which allows direct bus drive.
