Nothing is assigned.
In an attempt to write to these bits, write "0". The value, if read, turns out to be "0".

Note 1: The above diagram shows an instance in which the D-A register is assigned 2A16.
Note 2: The same circuit as this is also used for D-A1.
Note 3: To reduce the current consumption when the D-A converter is not used, set the D-A output enable bit to "0" and set the D-A register to
"0016" so that no current flows in the resistors Rs and 2Rs.
