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
tended 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.
