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 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
programmed for internal weak pull-up on all inputs.
RA0 can also be analog input 0
RA1 can also be analog input 1
RA2 can also be analog input 2
RA3 can also be analog input 3 or analog reference
voltage
RA4 can also be the clock input to the Timer0 timer/
counter. Output is open drain type.
RA5 can also be analog input 4
the synchronous serial port.
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.
