2: This buffer is a Schmitt Trigger input when used in serial programming mode.
3: This buffer is a Schmitt Trigger input when configured as a general purpose I/O and a TTL input when used
PP
in the Parallel Slave Port Mode (for interfacing to a microprocessor port).

input.
Oscillator crystal output. Connects to crystal or reso-
nator 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.
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-ups on
all inputs.
P = power
ST = Schmitt Trigger input
Analog comparator input.
Analog comparator input.
Analog comparator input or V
Analog comparator input or comparator output.
Can be selected to be the clock input to the
Timer0 timer/counter or a comparator output.
Output is open drain type.
RB0 can also be selected as an 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.
PORTC is a bi-directional I/O port.
