Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-0
TRISD<7:0>: PORTD Tri-State Control bits
1 = PORTD pin configured as an input (tri-stated)
0 = PORTD pin configured as an output
Note 1: TRISD is not implemented on PIC16F722/723/726/PIC16LF722/723/726 devices, read as ‘0’.

U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-0
ANSD<7:0>: Analog Select between Analog or Digital Function on Pins RD<7:0>, 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.
2: ANSELD register is not implemented on the PIC16F722/723/726/PIC16LF722/723/726. Read as ‘0’.
