Clock input to Timer0. Must be tied to VSS or VDD, if not in use, to reduce
current consumption.
— Active-low Reset to device. Voltage on the MCLR/VPP pin must not
exceed VDD to avoid unintended entering of Programming mode.
— Programming voltage input
— Oscillator crystal input
— External clock source input
XTAL Oscillator crystal output. Connects to crystal or resonator in Crystal
Oscillator mode.
CMOS In RC mode, OSC2 pin outputs CLKOUT, which has 1/4 the frequency of
OSC1.
— Positive supply for logic and I/O pins
— Ground reference for logic and I/O pins
I/O = input/output
— = Not Used
TTL = TTL input
CMOS = CMOS output
XTAL = Crystal input/output
HV
= High Voltage
