TTL

PORTB<0> data input; weak pull-up when RBPU bit is cleared.

INT0

External Interrupt 0 input.

RB1/INT1

RB1

DIG

LATB<1> data output.

TTL

PORTB<1> data input; weak pull-up when RBPU bit is cleared.

INT1

External Interrupt 1 input.

RB2/INT2

RB2

DIG

LATB<2> data output.

TTL

PORTB<2> data input; weak pull-up when RBPU bit is cleared.

INT2

External Interrupt 2 input.

RB3/INT3/

CCP2

RB3

DIG

LATB<3> data output.

TTL

PORTB<3> data input; weak pull-up when RBPU bit is cleared.

INT3

External Interrupt 3 input.

CCP2(1)

DIG

CCP2 compare output and CCP2 PWM output; takes priority over port

data.

CCP2 capture input.

RB4/KBI0

RB4

DIG

LATB<4> data output.

TTL

PORTB<4> data input; weak pull-up when RBPU bit is cleared.

KBI0

TTL

Interrupt on pin change.

RB5/KBI1

RB5

DIG

LATB<5> data output

TTL

PORTB<5> data input; weak pull-up when RBPU bit is cleared.

KBI1

TTL

Interrupt on pin change.

RB6/KBI2/PGC

RB6

DIG

LATB<6> data output

TTL

PORTB<6> data input; weak pull-up when RBPU bit is cleared.

KBI2

TTL

Interrupt on pin change.

PGC

Serial execution (ICSP™) clock input for ICSP and ICD operation(2).

RB7/KBI3/PGD

RB7

DIG

LATB<7> data output.

TTL

PORTB<7> data input; weak pull-up when RBPU bit is cleared.

KBI3

TTL

Interrupt on pin change.

PGD

DIG

Serial execution data output for ICSP and ICD operation(2).

Serial execution data input for ICSP and ICD operation(2).

Legend:

PWR = Power Supply, O = Output, I = Input, ANA = Analog Signal, DIG = Digital Output, ST = Schmitt Buffer Input,

TTL = TTL Buffer Input, x = Don’t care (TRIS bit does not affect port direction or is overridden for this option).

Note

Alternate assignment for CCP2 when the CCP2MX configuration bit is cleared (Microprocessor, Extended

Microcontroller and Microcontroller with Boot Block modes, 80-pin devices only). Default assignment is RC1.

All other pin functions are disabled when ICSP or ICD operations are enabled.
