Advance Information DS30275A-page 31 TABLE 3-3 PORTB FUNCTIONS TABLE 3-4 SUMMARY OF REGISTERS ASSOCIATED WITH PORTB 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. Address Name Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 Value on: POR, BOR Value on all other resets 06h, 106h PORTB RB7 RB6 RB5 RB4 RB3 RB2 RB1 RB0 xxxx 11xx uuuu 11uu 86h, 186h TRISB PORTB Data Direction Register 1111 1111 1111 1111 81h, 181h OPTION_REG RBPU INTEDG T0CS T0SE PSA PS2 PS1 PS0 1111 1111 1111 1111 9Fh ADCON1 ADFM VCFG2 VCFG1 VCFG0 PCFG3 PCFG2 PCFG1 PCFG0 0000 0000 0000 0000 Legend: x = unknown, u = unchanged.
