Description
OSC1/CLKIN
Oscillator input in crystal/resonator or RC oscillator mode.
External clock input in external clock mode.
Oscillator output. Connects to crystal or resonator in crystal
oscillator mode. In RC oscillator or external clock modes
OSC2 pin outputs CLKOUT which has one fourth the fre-
quency of OSC1 and denotes the instruction cycle rate.
Master clear (reset) input. This is the active low reset input to
the chip.
PORTA is a bi-directional I/O Port except for RA0 and RA1
which are input only.
RA0/INT can also be selected as an external interrupt
input. Interrupt can be configured to be on positive or
negative edge.
Can also be selected to be the clock input to the TMR0
timer/counter.
High voltage, high current open drain input/output port
pins.
High voltage, high current open drain input/output port
pins.
RA4/RX/DT can also be selected as the USART Asyn-
chronous Receive or USART Synchronous Data.
RA5/TX/CK can also be selected as the USART Asyn-
chronous Transmit or USART Synchronous Clock.
PORTB is a bi-directional I/O Port.
RB0/CAP1 can also be the CAP1 input pin.
RB1/CAP2 can also be the CAP2 input pin.
RB2/PWM1 can also be the PWM1 output pin.
RB3/PWM2 can also be the PWM2 output pin.
RB4/TCLK12 can also be the external clock input to
Timer1 and Timer2.
RB5/TCLK3 can also be the external clock input to
Timer3.

PORTC is a bi-directional I/O Port.
This is also the lower half of the 16-bit wide system bus
in microprocessor mode or extended microcontroller
mode. In multiplexed system bus configuration, these
pins are address output as well as data input or output.
