TABLE 12-10: SUMMARY OF REGISTERS ASSOCIATED WITH PORTD
REGISTER 12-17: ANSELD: PORTD ANALOG SELECT REGISTER
U-0 U-0 U-0 U-0 R/W-1 R/W-1 R/W-1 R/W-1
ANSD3 ANSD2 ANSD1 ANSD0
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 7-4 Unimplemented: Read as ‘0
bit 3-0 ANSD<3:0>: Analog Select between Analog or Digital Function on pins RD<3:0>, respectively
1 = Analog input. Pin is assigned as analog input
(1)
. Digital input buffer disabled.
0 = Digital I/O. Pin is assigned to port or digital special function.
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 12-18: WPUD: WEAK PULL-UP PORTD 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
WPUD7 WPUD6 WPUD5 WPUD4 WPUD3 WPUD2 WPUD1 WPUD0
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 WPUD<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.
