Alternate Functions of Port C

The Port C pins with alternate functions are shown in Table 11-6.

Table 11-6. Port C Pins Alternate Functions

Port Pin

Alternate Function

PC7

D2A : DAC output

ADC10 (Analog Input Channel 10)

PC6

ACMP1 (Analog Comparator 1 Positive Input )

PC0

INT3

The alternate pin configuration is as follows:

• D2A – Bit 7

D2A, Digital to Analog output

• ADC10/ACMP1 – Bit 6

ADC10, Analog to Digital Converter, input channel 10.

ACMP1, 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.

• ADC9/AMP1+ – Bit 5

ADC9, Analog to Digital Converter, input channel 9.

AMP1+, Analog Differential Amplifier 1 Positive Input Channel.

• ADC8/AMP1- – Bit 4

ADC8, Analog to Digital Converter, input channel 8.

AMP1-, Analog Differential Amplifier 1 Negative Input Channel.

• T1/PSCOUT23 – Bit 3

T1, Timer/Counter1 counter source.

PSCOUT23: Output 3 of PSC 2.

• T0/PSCOUT22 – Bit 2

T0, Timer/Counter0 counter source.

PSCOUT22: Output 2 of PSC 2.
