Alternate Functions of Port D
The Port D pins with alternate functions are shown in
Table 9-6.
The alternate pin configuration is as follows:
• ADC10/PSCINrA – Bit 7
ADC10, Analog to Digital Converter, input channel 10.
PCSINrA, PSCR First Alternate Digital Input.
• APM0+ – Bit 6
AMP0+, Analog Differential Amplifier 0 Positive Input Channel.
• AMP0-/ADC7 – Bit 5
AMP0-, Analog Differential Amplifier 0 Negative Input Channel.
ADC7, Analog to Digital Converter, input channel 7
• ACMP3M/ADC4/PSCIN2A – Bit 4
ACMP3M, Analog Comparator 3 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.
ADC4, Analog to Digital Converter, input channel 4.
PCSIN2A, PSC 2 Alternate Digital Input.
