This buffer is a Schmitt Trigger input when configured as an external interrupt or LVP mode.
This buffer is a Schmitt Trigger input when used in Serial Programming mode.
This buffer is a Schmitt Trigger input when configured as general purpose I/O and a TTL input when used in the Parallel
Slave Port mode (for interfacing to a microprocessor bus).
This buffer is a Schmitt Trigger input when configured in RC Oscillator mode and a CMOS input otherwise.

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 CLKO,
which has 1/4 the frequency of OSC1, and denotes the
instruction cycle rate.
Master Clear (Reset) input or programming voltage input or
High Voltage Test mode control. 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.
PORTC is a bi-directional I/O port.
RA0 can also be analog input 0.
RA1 can also be analog input 1.
RA2 can also be analog input 2 or negative analog
reference voltage.
RA3 can also be analog input 3 or positive 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.
RB0 can also be the external interrupt pin.
RB3 can also be the low voltage programming input.
Interrupt-on-change pin.
Interrupt-on-change pin.
Interrupt-on-change pin or In-Circuit Debugger pin.
Serial programming clock.
Interrupt-on-change pin or In-Circuit Debugger pin.
Serial programming data.
RC0 can also be the Timer1 oscillator output or a Timer1
clock input.
RC1 can also be the Timer1 oscillator input.
RC2 can also be the Capture1 input/Compare1 output/
PWM1 output.
RC6 can also be the USART Asynchronous Transmit or
Synchronous Clock.
RC7 can also be the USART Asynchronous Receive or
Synchronous Data.
