The pin function is switched as shown below according to the combination of the register setting
of the LPC and the P80DDR bit.

The pin function is switched as shown below according to the combination of the IIC0AS and
IIC0BS bits in PTCNT1, ICE bit in ICCR of IIC_0, and the P97DDR bit. When the ISS15 bit in
ISSR16 is cleared to 0 and the IRQ15E bit in IER16 of the interrupt controller is set to 1, this pin
can be used as the
IRQ15
input pin.

Note: To use this pin as SDA0, clear the IIC0AS and IIC0BS bits in PTCNT1 to 0. The output
format for SDA0 is NMOS output only and direct bus drive is possible. When this pin is used
as the P97 output pin, the output format is NMOS push-pull.
