one of one-hundred twenty-eight wiper positions along the
resistive array.
Bringing CS HIGH after INC is HIGH will cause the wiper
value to be locked until power down (further changes in CS
and INC will not change the wiper position). Otherwise, INC
should be brought HIGH after CS to allow continued wiper
changes.
The state of U/D may be changed while CS remains LOW.
This allows the host system to enable the device and then
move the wiper up and down until the proper trim is attained.
During initial power-up CS must go high along with or before
V
CC
to avoid an accidental tap position change.
