TABLE 5-3: PORTB FUNCTIONS
TABLE 5-4: SUMMARY OF REGISTERS ASSOCIATED WITH PORTB
Name Bit # 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.
