Description
Oscillator crystal input/external clock source input.
Oscillator crystal output. Connects to crystal or resonator in crystal
oscillator mode. In RC mode, the pin outputs CLKOUT which has
1/4 the frequency of OSC1, and denotes the instruction cycle rate.
Master clear reset input or 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 pro-
grammed for internal weak pull-up on all inputs.
Ground reference for logic and I/O pins.
Positive supply for logic and I/O pins.
RA4 can also be the clock input to the Timer0 timer/counter.
Output is open drain type.
RB0 can also be the external interrupt pin.
Interrupt on change pin.
Interrupt on change pin.
Interrupt on change pin. Serial programming clock.
Interrupt on change pin. Serial programming data.
P = power
ST = Schmitt Trigger input
