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.
Master Clear (Reset) input/programming voltage
input. This pin is an active low RESET to the device.
PORTA is a bi-directional I/O port.
PORTB is a bi-directional I/O port. PORTB can be
software programmed for internal weak pull-up on
all inputs.
Ground reference for logic and I/O pins.
Positive supply for logic and I/O pins.
P = Power
ST = Schmitt Trigger input
interrupt pin.
Can also be selected to be the clock input to the
TMR0 timer/counter. Output is open drain type.
RB0/INT can also be selected as an external
Interrupt-on-change pin.
Interrupt-on-change pin.
Interrupt-on-change pin.
Serial programming clock.
Interrupt-on-change pin.
Serial programming data.
