Clock input to Timer0. Must be tied to V
reduce current consumption.
Active-low Reset to device. Voltage on the MCLR/V
not exceed V
mode.
Programming voltage input
Oscillator crystal input
Oscillator crystal output. Connects to crystal or resonator in
Crystal Oscillator mode.
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
Unused, do not connect
