SDA, 2-wire Serial Interface Data: When the TWEN bit in TWCR is set (one) to enable the
2-wire Serial Interface, pin PC4 is disconnected from the port and becomes the Serial Data
I/O pin for the 2-wire Serial Interface. In this mode, there is a spike filter on the pin to sup-
press spikes shorter than 50 ns on the input signal, and the pin is driven by an open drain
driver with slew-rate limitation.
PC4 can also be used as ADC input Channel 4. Note that ADC input channel 4 uses digital
power.
PCINT12: Pin Change Interrupt source 12. The PC4 pin can serve as an external interrupt
source.
PC3 can also be used as ADC input Channel 3. Note that ADC input channel 3 uses analog
power.
PCINT11: Pin Change Interrupt source 11. The PC3 pin can serve as an external interrupt
source.
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.
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.
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.
