6.5.1
The ANSELD register (Register 6-17) is used to
configure the Input mode of an I/O pin to analog.
Setting the appropriate ANSELD bit high will cause all
digital reads on the pin to be read as ‘0’ and allow
analog functions on the pin to operate correctly.
The state of the ANSELD bits has no affect on digital
output functions. A pin with TRIS clear and ANSEL set
will still operate as a digital output, but the Input mode

TRISD is not implemented on PIC16F1933/1936/1938 devices, read as ‘0’.
PORTD implemented on PIC16F1934/1937/1939/PIC16LF1934/1937/1939 devices only.
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.

The ANSELD register must be initialized
to configure an analog channel as a digital
input. Pins configured as analog inputs will
read ‘0’.
