Bi-directional I/O port
Bi-directional I/O port
Bi-directional I/O port
Clock input to Timer0. Must be tied to V
to reduce current consumption.
Master clear (reset) input. This pin is an active low reset to the
device.
Oscillator crystal input/external clock source 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, and denotes
the instruction cycle rate.
Positive supply for logic and I/O pins.
Ground reference for logic and I/O pins.
Unused, do not connect
