I
ST Clock input to Timer0. Must be tied to VSS or VDD, if not in
use, to reduce current consumption.
MCLR/VPP

I
ST Master clear (reset) input/programming voltage input. This
pin is an active low reset to the device. Voltage on the
MCLR/VPP pin must not exceed VDD to avoid unintended
entering of programming mode.
OSC1/CLKIN

I
ST Oscillator crystal input/external clock source input.
OSC2/CLKOUT
15
17 O
— 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.

Legend: I = input, O = output, I/O = input/output,
P = power, — = Not Used, TTL = TTL input,
ST = Schmitt Trigger input
Positive supply for logic and I/O pins.
Ground reference for logic and I/O pins.
