Oscillator crystal input/external clock source input.
Oscillator crystal output. Connects to crystal or resonator in
crystal oscillator mode. In RC mode, the 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.
PORTC is a bi-directional I/O port.
Ground reference for logic and I/O pins.
Positive supply for logic and I/O pins.
RA0 can also be analog input0.
RA1 can also be analog input1.
RA2 can also be analog input2 or negative analog
reference voltage.
RA3 can also be analog input3 or positive analog
reference voltage.
RA4 can also be the clock input to the Timer0
module. Output is open drain type.
RA5 can also be analog input4 or the slave select
for the synchronous serial port.
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 Timer1
clock input.
RC1 can also be the Timer1 oscillator input or Capture2
input/Compare2 output/PWM2 output.
RC2 can also be the Capture1 input/Compare1 output/
PWM1 output.
RC3 can also be the synchronous serial clock input/output
for both SPI and I
RC4 can also be the SPI Data In (SPI mode) or
data I/O (I
RC5 can also be the SPI Data Out (SPI mode).
RC6 can also be the USART Asynchronous Transmit or
Synchronous Clock.
RC7 can also be the USART Asynchronous Receive or
Synchronous Data.
