REGISTER 12-27: ANSELG: PORTG ANALOG SELECT REGISTER
U-0 U-0 U-0 R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1 U-0
— — — ANSG4 ANSG3 ANSG2 ANSG1 —
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 7-5 Unimplemented: Read as ‘0’.
bit 4-1 ANSG<4:1>: Analog Select between Analog or Digital Function on Pins RG<4:0>, 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.
bit 0 Unimplemented: Read as ‘0’.
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 12-28: WPUG: WEAK PULL-UP PORTG REGISTER
U-0 U-0 R/W-1/1 U-0 U-0 U-0 U-0 U-0
— —WPUG5— — — — —
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 WPUG5: Weak Pull-up Register bits
1 = Pull-up enabled
0 = Pull-up disabled
bit 4-0 Unimplemented: Read as ‘0’.
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.
