112 / 386 page  PIC18F6X2X/8X2X DS39612A-page 110 Advance Information 2003 Microchip Technology Inc. TABLE 10-3: PORTB FUNCTIONS TABLE 10-4: SUMMARY OF REGISTERS ASSOCIATED WITH PORTB Name Bit# Buffer Function RB0/INT0 bit 0 TTL/ST(1) Input/output pin or external interrupt input 0. Internal software programmable weak pull-up. RB1/INT1 bit 1 TTL/ST(1) Input/output pin or external interrupt input 1. Internal software programmable weak pull-up. RB2/INT2 bit 2 TTL/ST(1) Input/output pin or external interrupt input 2. Internal software programmable weak pull-up. RB3/INT3/ CCP2(3)/P2A(3) bit 3 TTL/ST(4) Input/output pin, external interrupt input 3, Capture2 input/Compare2 output/PWM2 output, or Enhanced PWM output P2A. Internal software programmable weak pull-up. RB4/KBI0 bit 4 TTL Input/output pin (with interrupt-on-change). Internal software programmable weak pull-up. RB5/KBI1/PGM bit 5 TTL/ST(2) Input/output pin (with interrupt-on-change). Internal software programmable weak pull-up. Low voltage ICSP enable pin. RB6/KBI2/PGC bit 6 TTL/ST(2) Input/output pin (with interrupt-on-change). Internal software programmable weak pull-up. Serial programming clock. RB7/KBI3/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. 3: Valid for PIC18F8X2X devices in all operating modes except Microcontroller mode when CCP2MX is not set. RC1 is the default assignment for CCP2/PA2 when CCP2MX is set in all devices; RE7 is the alternate assignment for PIC18F8X2X devices in Microcontroller mode when CCP2MX is clear. 4: This buffer is a Schmitt Trigger input when configured as the CCP2 input.
