• ADC2/PCINT10 – Port C, Bit 2
PC2 can also be used as ADC input channel 2. Note that ADC input channel 2 uses analog power.
PCINT10: Pin change interrupt source 10. The PC2 pin can serve as an external interrupt source.
• 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.
Table 5-36 and Table 5-37 relate the alternate functions of port C to the overriding signals shown in Figure 5-26 on page 82.

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.
