Alternate Functions of Port E
The Port E pins with alternate functions are shown in Table 11-12.
Table 11-12. Port E Pins Alternate Functions
Port Pin Alternate Function
XTAL2: XTAL Output
PE2
ADC0 (Analog Input Channel 0)
XTAL1: XTAL Input
PE1
OC0B (Timer 0 Output Compare B)
RESET# (Reset Input)
PE0
OCD (On Chip Debug I/O)
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.
