Pin function
The pin function is switched as shown below according to the combination of the ICE bit in
ICCRA of the IIC3_3 and the PC3DDR bit. When this pin is used as the PC3 output pin, the
output format is NMOS push-pull output. The output format for SDA3 is NMOS open-drain
output, and direct bus drive is possible.
