T0CKI 1 1 2 I ST Clock input to Timer0. Must be tied to V
SS or VDD, if not in
use, to reduce current consumption.
MCLR
28 28 28 I ST Master clear (RESET) input. This pin is an active low
RESET to the device.
OSC1/CLKIN 27 27 27 I ST Oscillator crystal input/external clock source input.
OSC2/CLKOUT 26 26 26 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.
V
DD 2 2 3,4 P — Positive supply for logic and I/O pins.
VSS 4 4 1,14 P — Ground reference for logic and I/O pins.
N/C 3,5 3,5 — — — Unused, do not connect.
Legend: I = input, O = output, I/O = input/output, P = power, — = Not Used, TTL = TTL input, ST = Schmitt Trigger
