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
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.
RA3 can also be analog input3 or 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.
Interrupt on change pin.
Interrupt on change pin.
Interrupt on change pin. Serial programming clock.
Interrupt on change pin. Serial programming data.
RC0 can also be the Timer1 oscillator output or Timer1 clock
input.
RC1 can also be the Timer1 oscillator input.
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).
