Alternate Functions of Port D

The Port D pins with alternate functions are shown in Table 30.

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 Analog 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 Analog 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.
