Alternate Functions of Port D
The Port D pins with alternate functions are shown in
Table 13-9.
The alternate pin configuration is as follows:
• ACMP0/PCINT23 – Bit 7
ACMP0, Analog Comparator 0 Positive Input. Configure the port pin as input with the internal
pull-up switched off to avoid the digital port function from interfering with the function of the Ana-
log Comparator.
PCINT23, Pin Change Interrupt 23.
• ADC3/ACMPN2/INT0/PCINT22 – Bit 6
ADC3, Analog to Digital Converter, input channel 3.
