TABLE 12-6: SUMMARY OF REGISTERS ASSOCIATED WITH PORTB REGISTER 12-9: ANSELB: PORTB ANALOG SELECT REGISTER U-0 U-0 R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1 — — ANSB5 ANSB4 ANSB3 ANSB2 ANSB1 ANSB0 bit 7 bit 0 Legend: R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’ u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets ‘1’ = Bit is set ‘0’ = Bit is cleared bit 7-6 Unimplemented: Read as ‘0’ bit 5-0 ANSB<5:0> : Analog Select between Analog or Digital Function on pins RB<5:0>, respectively 0 = Digital I/O. Pin is assigned to port or digital special function. 1 = Analog input. Pin is assigned as analog input(1). Digital input buffer disabled. Note 1: When setting a pin to an analog input, the corresponding TRIS bit must be set to Input mode in order to allow external control of the voltage on the pin. REGISTER 12-10: WPUB: WEAK PULL-UP PORTB REGISTER R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1 WPUB7 WPUB6 WPUB5 WPUB4 WPUB3 WPUB2 WPUB1 WPUB0 bit 7 bit 0 Legend: R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’ u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets ‘1’ = Bit is set ‘0’ = Bit is cleared bit 7-0 WPUB<7:0> : Weak Pull-up Register bits 1 = Pull-up enabled 0 = Pull-up disabled Note 1: Global WPUEN bit of the OPTION_REG register must be cleared for individual pull-ups to be enabled. 2: The weak pull-up device is automatically disabled if the pin is in configured as an output. Name Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 Register on Page APFCON — — — — — — T3CKISEL CCP2SEL 124 ANSELB — — ANSB5 ANSB4 ANSB3 ANSB2 ANSB1 ANSB0 124 LATB LATB7 LATB6 LATB5 LATB4 LATB3 LATB2 LATB1 LATB0 123 PORTB RB7 RB6 RB5 RB4 RB3 RB2 RB1 RB0 123 TRISB TRISB7 TRISB6 TRISB5 TRISB4 TRISB3 TRISB2 TRISB1 TRISB0 123 WPUB WPUB7 WPUB6 WPUB5 WPUB4 WPUB3 WPUB2 WPUB1 WPUB0 124 Legend: x = unknown, u = unchanged, - = unimplemented locations read as ‘0’. Shaded cells are not used by PORTB. |
