PCINT9: Pin Change Interrupt source 9. The PC1 pin can serve as an external interrupt source.
• ADC0/PCINT8 – Port C, bit 0
PC0 can also be used as ADC input Channel 0. Note that ADC input channel 0 uses analog
power.
PCINT8: Pin Change Interrupt source 8. The PC0 pin can serve as an external interrupt source.
