Name

Bit#

Buffer

Function

RB0/INT

bit0

TTL/ST

Input/output pin or external interrupt input. Internal software

programmable weak pull-up. This buffer is a Schmitt Trigger input when

configured as the external interrupt.

RB1

bit1

TTL

Input/output pin. Internal software programmable weak pull-up.

RB2

bit2

TTL

Input/output pin. Internal software programmable weak pull-up.

RB3

bit3

TTL

Input/output pin. Internal software programmable weak pull-up.

RB4

bit4

TTL

Input/output pin (with interrupt-on-change). Internal software programmable

weak pull-up.

RB5

bit5

TTL

Input/output pin (with interrupt-on-change). Internal software programmable

weak pull-up.

RB6

bit6

TTL/ST Input/output pin (with interrupt-on-change). Internal software programmable

weak pull-up. Serial programming clock. This buffer is a Schmitt Trigger

input when used in Serial Programming mode.

RB7

bit7

TTL/ST Input/output pin (with interrupt-on-change). Internal software programmable

weak pull-up. Serial programming data. This buffer is a Schmitt Trigger

input when used in Serial Programming mode.

Legend: TTL = TTL input, ST = Schmitt Trigger input
