19.3.4 Alternate Functions of Port E

The Port E pins with alternate functions are shown in this table:

Table 19-12. Port E Pins Alternate Functions
Port PinAlternate Function
PE3

ADC7 (ADC Input Channel 7)

PE2

ADC6 (ADC Input Channel 6)

PE1
PE0

ACO (AC Output Channel)

The alternate pin configuration is as follows:

  • ADC7 – Port E, Bit 3
    • PE3 can also be used as ADC input Channel 7.
  • ADC6 – Port E, Bit 2
    • PE2 can also be used as ADC input Channel 6.
  • Port E, Bit 1
  • ACO – Port E, Bit 0
    • PE0 can also be used as Analog Comparator output.

Table 19-13 relate the alternate functions of Port E to the overriding signals shown in Figure 19-5.
