• ADC1/PCINT9 – Port C, Bit 1
PC1 can also be used as ADC input Channel 1. Note that ADC input channel 1 uses analog power.
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.

When enabled, the 2-wire Serial Interface enables slew-rate controls on the output pins PC4 and PC5. This is 
not shown in the figure. In addition, spike filters are connected between the AIO outputs shown in the port 
figure and the digital logic of the TWI module.
