TABLE 3-3 PORTB FUNCTIONS
Name
Bit#
Buffer Function
RB0/INT
bit0 TTL/ST(1) Input/output pin or external interrupt input. Internal software
programmable weak pull-up.
RB1/SS
bit1 TTL/ST(3) Input/output pin or SSP slave select. Internal software programmable
weak pull-up.
RB2/AN8
bit2
TTL Input/output pin or analog input8. Internal software programmable
weak pull-up.
RB3/AN9/LVDIN bit3
TTL Input/output pin or analog input9 or Low-voltage detect input. 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.
RB7
bit7 TTL/ST(2) Input/output pin (with interrupt on change). Internal software
programmable weak pull-up. Serial programming data.
Legend: TTL = TTL input, ST = Schmitt Trigger input
Note 1: This buffer is a Schmitt Trigger input when configured as the external interrupt.
2: This buffer is a Schmitt Trigger input when used in serial programming mode.
3: This buffer is a Schmitt Trigger input when used as the SSP slave select.
