Preliminary
Bi-directional I/O port
Bi-directional I/O port
Clock input to Timer0. Must be tied to V
use, to reduce current consumption.
Master clear (reset) input/programming voltage input. This
pin is an active low reset to the device. Voltage on the
MCLR/V
entering of programming mode.
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.
