ATmega48/88/168 Automotive
• SDA/ADC4/PCINT12 – Port C, Bit 4
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 suppress 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.
• ADC3/PCINT11 – Port C, Bit 3
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.
• 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.
