The alternate pin configuration is as follows:
9.3.3 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 Ana-
log Comparator.
ADC4: Analog to Digital Converter, input channel 4.
PCSIN2A: PSC 2 Alternate Digital Input.
Table 9-6. Port D pins alternate functions.
