19.3.4 Alternate Functions of Port E
The Port E pins with alternate functions are shown in this table:
Port Pin | Alternate 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.
