Description
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 pro-
grammed for internal weak pull-up on all inputs.
PORTC is a bi-directional I/O port.
Ground reference for A/D converter
Positive supply for A/D converter
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
input or internal voltage reference low
RA3 can also be analog input3 or positive analog reference voltage
input or internal voltage reference high
RA4 can also be the clock input to the Timer0 module. Output is
open drain type.
RB0 can also be the external interrupt pin.
RB1 can also be the SSP slave select
RB2 can also be analog input8
RB3 can also be analog input9 or the low voltage detect input
reference

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.
