14.3.4. Alternate Functions of Port E
The Port E pins with alternate functions are shown in this table:
Table 14-12. Port E Pins Alternate Functions
Port Pin Alternate Function
PE2 XTAL2 (XTAL output)
ADC0 (Analog Input Channel 0)
PCINT26 (Pin Change Interrupt 26)
PE1 XTAL1 (XTAL input)
OC0B (Timer 0 Output Compare B)
PCINT25 (Pin Change Interrupt 25)
PE0 RESET# (Reset input)
OCD (On Chip Debug I/O)
PCINT24 (Pin Change Interrupt 24)
The alternate pin configuration is as follows:
• PCINT26/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.
– PCINT26, Pin Change Interrupt 26.
