Pin Functions

• P67/IRQ7/KIN7/TMOX
The function of port 6 pins is switched as shown below according to the combination of the
TMOXS bit in PTCNT0, OS3 to OS0 bits in TCSR of TMR_X, and the P67DDR bit.
When the KMIMR7 bit in KMIMR of the interrupt controller is cleared to 0, this pin can be
used as the KIN7 input pin. When the ISS7 bit in ISSR is cleared to 0 and the IRQ7E bit in
IER of the interrupt controller is set to 1, this pin can be used as the IRQ7 interrupt input pin.
