Alternate Functions of Port D
The Port D pins with alternate functions are shown in
Table 12. Port D Pins Alternate Functions
The alternate pin configuration is as follows:
• ACMP0 – 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.
• ADC3/ACMPM/INT0 – Bit 6
ADC3, Analog to Digital Converter, input channel 3.
ACMPM, Analog Comparators Negative 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.
INT0, External Interrupt source 0. This pin can serve as an external interrupt source to the MCU.
• ADC2/ACMP2 – Bit 5
ADC2, Analog to Digital Converter, input channel 2.
ACMP2, Analog Comparator 1 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.
• ADC1/ICP1/SCK_A – Bit 4
ADC1, Analog to Digital Converter, input channel 1.
