(5) PG3/SCL2/
ExIRQ11
The pin function is switched as shown below according to the combination of the register setting
of the IIC and the PG3DDR bit. When the ISS11 bit in ISSR16 is set to 1 and the IRQ11E bit in
IER16 of the interrupt controller is set to 1, this pin can be used as the
ExIRQ11
input pin.

Note: The output format for SCL2 is NMOS output only, and direct bus drive is possible. When
this pin is used as the PG3 output pin, the output format is NMOS push-pull.
(6) PG2/SDA2/
ExIRQ10
The pin function is switched as shown below according to the combination of the register setting
of the IIC and the PG2DDR bit. When the ISS10 bit in ISSR16 is set to 1 and the IRQ10E bit in
IER16 of the interrupt controller is set to 1, this pin can be used as the
ExIRQ10
input pin.
