Alternate Functions of Port E
Table 14. Overriding Signals for Alternate Functions in PD3..PD0
The Port E pins with alternate functions are shown in
Table 15. Port E Pins Alternate Functions
The alternate pin configuration is as follows:
• XTAL2/ADC0 – Bit 2
XTAL2: Chip clock Oscillator pin 2. Used as clock pin for crystal Oscillator or Low-frequency
crystal Oscillator. When used as a clock pin, the pin can not be used as an I/O pin.
ADC0, Analog to Digital Converter, input channel 0.
• XTAL1/OC0B – Bit 1
