Pin function
The pin function is switched as shown below according to the combination of the ICE bit in
ICCR of IIC_0 and the P80DDR bit.
When the ISS8 bit in ISSR16 of the interrupt controller is set to 1, this pin can be used as the
ExIRQ8 input pin. To use this pin as the ExIRQ8 input pin, clear the P80DDR bit to 0.
When this pin is used as the P80 output pin, the output format is NMOS push-pull output. The
output format for SCL0 is NMOS open-drain output, and direct bus drive is possible.
