116 / 222 page  MCP19111 DS22331A-page 116 2013 Microchip Technology Inc. REGISTER 19-8: WPUGPB: WEAK PULL-UP PORTGPB REGISTER R/W-1 R/W-1 R/W-1 R/W-1 U-0 R/W-1 R/W-1 U-0 WPUB7 WPUB6 WPUB5 WPUB4 — WPUB2 WPUB1 — bit 7 bit 0 Legend: R = Readable bit P = Programmable bit U = Unimplemented bit, read as ‘0’ -n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown bit 7-4 WPUB<7:4>: Weak Pull-up Register bit 1 = Pull-up enabled 0 = Pull-up disabled bit 3 Unimplemented: Read as ‘0’ bit 2-1 WPUB<2:1>: Weak Pull-up Register bit 1 = Pull-up enabled 0 = Pull-up disabled bit 0 Unimplemented: Read as ‘0’ Note 1: The weak pull-up device is enabled only when the global RAPU bit is enabled, the pin is in Input mode (TRISGPA = 1), the individual WPUB bit is enabled (WPUB = 1), and the pin is not configured as an analog input. REGISTER 19-9: ANSELB: ANALOG SELECT PORTGPB REGISTER U-0 U-0 R/W-1 R/W-1 U-0 R/W-1 R/W-1 U-0 — — ANSB5 ANSB4 — ANSB2 ANSB1 — bit 7 bit 0 Legend: R = Readable bit P = Programmable bit U = Unimplemented bit, read as ‘0’ -n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown bit 7-6 Unimplemented: Read as ‘0’ bit 5-4 ANSB<5:4>: Analog Select PORTGPB Register bit 1 = Analog input. Pin is assigned as analog input(1). 0 = Digital I/O. Pin is assigned to port or special function. bit 3 Unimplemented: Read as ‘0’ bit 2-1 ANSB<2:1>: Analog Select PORTGPB Register bit 1 = Analog input. Pin is assigned as analog input(1). 0 = Digital I/O. Pin is assigned to port or special function. bit 0 Unimplemented: Read as ‘0’ Note 1: Setting a pin to an analog input automatically disables the digital input circuitry, weak pull-ups and interrupt-on-change if available. The corresponding TRIS bit must be set to Input mode in order to allow external control of the voltage on the pin. |
