Description

OSC1/CLKIN

Oscillator input in crystal/resonator or RC oscillator

mode. External clock input in external clock mode.

OSC2/CLKOUT

—

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 frequency (FOSC/4) of OSC1 and

denotes the instruction cycle rate.

MCLR/VPP

I/P

Master clear (reset) input or Programming Voltage

(VPP) input. This is the active low reset input to the

device.

PORTA pins have individual differentiations that are

listed in the following descriptions:

RA0/INT

RA0 can also be selected as an external inter-

rupt input. Interrupt can be conﬁgured to be on

positive or negative edge. Input only pin.

RA1/T0CKI

RA1 can also be selected as an external inter-

rupt input, and the interrupt can be conﬁgured

to be on positive or negative edge. RA1 can

also be selected to be the clock input to the

Timer0 timer/counter. Input only pin.

RA2/SS/SCL

I/O (2)

RA2 can also be used as the slave select input

for the SPI or the clock input for the I2C bus.

High voltage, high current, open drain port pin.

RA3/SDI/SDA

I/O (2)

RA3 can also be used as the data input for the

SPI or the data for the I2C bus.

High voltage, high current, open drain port pin.

RA4/RX1/DT1

I/O (1)

RA4 can also be selected as the USART1 (SCI)

Asynchronous Receive or USART1 (SCI)

Synchronous Data.

Output available from USART only.

RA5/TX1/CK1

I/O (1)

RA5 can also be selected as the USART1 (SCI)

Asynchronous Transmit or USART1 (SCI)

Synchronous Clock.

Output available from USART only.

PORTB is a bi-directional I/O Port with software

conﬁgurable weak pull-ups.

RB0/CAP1

I/O

RB0 can also be the Capture1 input pin.

RB1/CAP2

I/O

RB1 can also be the Capture2 input pin.

RB2/PWM1

I/O

RB2 can also be the PWM1 output pin.

RB3/PWM2

I/O

RB3 can also be the PWM2 output pin.

RB4/TCLK12

I/O

RB4 can also be the external clock input to

Timer1 and Timer2.

RB5/TCLK3

I/O

RB5 can also be the external clock input to

Timer3.

RB6/SCK

I/O

RB6 can also be used as the master/slave clock

for the SPI.

RB7/SDO

I/O

RB7 can also be used as the data output for the

SPI.

Legend: I = Input only;

O = Output only;

I/O = Input/Output;

P = Power;

— = Not Used;

TTL = TTL input;

ST = Schmitt Trigger input.

Note 1: The output is only available by the peripheral operation.

2: Open Drain input/output pin. Pin forced to input upon any device reset.
