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 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 PIC16F1933/1936/1938. Read as ‘0’.
3: PORTD implemented on PIC16F1934/1937/1939/PIC16LF1934/1937/1939 devices only.

Legend: x = unknown, u = unchanged, – = unimplemented locations read as ‘0’. Shaded cells are not used by PORTD.
Note 1: These registers are not implemented on the PIC16F1933/1936/1938 devices, read as ‘0’.
2: The Capacitive Sensing Reference Mode (CPSRM) bit is not available for the PIC16F/LF1934/1936 devices.
