Buffer
Type
Description
ST/CMOS
—
Oscillator crystal input or external clock source input. This
buffer is a Schmitt Trigger input when configured in RC
oscillator mode and a CMOS input otherwise.
Oscillator crystal output. Connects to crystal or resonator in
crystal oscillator mode. In RC mode, OSC2 pin outputs
CLKOUT, which has 1/4 the frequency of OSC1 and denotes
the instruction cycle rate.
ST
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.
TTL
RA0 can also be Analog input0.
TTL
RA1 can also be Analog input1.
TTL
RA2 can also be Analog input2.
TTL
RA3 can also be Analog input3 or A/D Voltage
Reference.
ST
RA4 can also be the clock input to the Timer0
timer/counter. Output is open drain type.
TTL
RA5 can be the slave select for the synchronous serial port
or Analog input4.
PORTB is a bi-directional I/O port. PORTB can be software
programmed for internal weak pull-ups on all inputs.
TTL/ST
RB0 can also be the external interrupt pin. This buffer is a
Schmitt Trigger input when configured as an
external interrupt.

TTL
Interrupt-on-change pin.
TTL/ST
Interrupt-on-change pin. Serial programming clock. This
buffer is a Schmitt Trigger input when used in Serial
Programming mode.
TTL/ST
Interrupt-on-change pin. Serial programming data. This
buffer is a Schmitt Trigger input when used in Serial
Programming mode.
PORTC is a bi-directional I/O port.
ST
RC0 can also be the Timer1 oscillator output or Timer1
clock input.
ST
RC1 can also be the Timer1 oscillator input.
ST
RC2 can also be the Capture1 input/Compare1
output/PWM1 output.
ST
RC3 can also be the synchronous serial clock input/
output for both SPI and I2C modes.
ST
RC4 can also be the SPI Data In (SPI mode) or
data I/O (I2C mode).
ST
RC5 can also be the SPI Data Out (SPI mode).
