(3) PG5/ExSCLA/
ExIRQ13
The pin function is switched as shown below according to the combination of the register setting
of PTCNT1 and the PG5DDR bit. When the ISS13 bit in ISSR16 is set to 1 and the IRQ13E bit in
IER16 of the interrupt controller is set to 1, this pin can be used as the
ExIRQ13
input pin.

Note: The output format for ExSCLA is NMOS output only, and direct bus drive is possible. When
this pin is used as the PG5 output pin, the output format is NMOS push-pull.
(4) PG4/ExSDAA/
ExIRQ12
The pin function is switched as shown below according to the combination of the register setting
of PTCNT1 and the PG4DDR bit. When the ISS12 bit in ISSR16 is set to 1 and the IRQ12E bit in
IER16 of the interrupt controller is set to 1, this pin can be used as the
ExIRQ12
input pin.
