Buffer Type
Function
RB0/INT
bit0
TTL/ST(1)
Input/output or external interrupt input. Internal software programmable
weak pull-up.
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(2)
Input/output pin (with interrupt on change). Internal software
programmable weak pull-up. Serial programming clock pin.
RB7
bit7
TTL/ST(2)
Input/output pin (with interrupt on change). Internal software
programmable weak pull-up. Serial programming data pin.
Legend: ST = Schmitt Trigger, TTL = TTL input
Note 1: This buffer is a Schmitt Trigger input when configured as the external interrupt.
Note 2: This buffer is a Schmitt Trigger input when used in serial programming mode.
