TABLE 5-4: SUMMARY OF REGISTERS ASSOCIATED WITH PORTB
Name Bit# Buffer Function
RB0/INT/AN12 bit 0 TTL/ST
(1)
Input/output pin or external interrupt input. Internal software
programmable weak pull-up or analog input.
RB1/AN10 bit 1 TTL Input/output pin. Internal software programmable weak pull-up or
analog input.
RB2/AN8 bit 2 TTL Input/output pin. Internal software programmable weak pull-up or
analog input.
RB3/CCP2/AN9 bit 3 TTL Input/output pin or Capture 2 input/Compare 2 output/PWM 2 output.
Internal software programmable weak pull-up or analog input.
RB4/AN11 bit 4 TTL Input/output pin (with interrupt-on-change). Internal software
programmable weak pull-up or analog input.
RB5/AN13/CCP3 bit 5 TTL Input/output pin (with interrupt-on-change). Internal software
programmable weak pull-up or analog input or Capture 2 input/
Compare 2 output/PWM 2 output.
RB6/PGC bit 6 TTL/ST
(2)
Input/output pin (with interrupt-on-change). Internal software
programmable weak pull-up. Serial programming clock.
RB7/PGD bit 7 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.
