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.
ANSELD register is not implemented on the PIC16F1933/1936/1938. Read as ‘0’.
PORTD implemented on PIC16F1934/1937/1939/PIC16LF1934/1937/1939 devices only.
x = unknown, u = unchanged, – = unimplemented locations read as ‘0’. Shaded cells are not used by PORTD.
These registers are not implemented on the PIC16F1933/1936/1938 devices, read as ‘0’.
The Capacitive Sensing Reference Mode (CPSRM) bit is not available for the PIC16F/LF1934/1936 devices.
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
