Description
Oscillator crystal input/external clock source input.
Oscillator crystal output. Connects to crystal or resonator in crys-
tal oscillator mode. In RC mode, the 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 logic and I/O pins.
Positive supply for logic and I/O pins.
RA4 can also be the clock input to the Timer0 timer/counter.
Output is open drain type.
RA5 can also be 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
clock input.
RC1 can also be the Timer1 oscillator input
input/Compare2 output/PWM2 output
RC2 can also be the Capture1 input/Compare1 out-
put/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
Synchronous Clock
RC7 can also be the USART Asynchronous Receive
Synchronous Data
