(* The upper 4 bits of bestTrim contains the answer for the course adjustment.*)
(* It is the smallest value that allows full scale trim with the lower 12 bits*)
(* zero out the lower 12 bits of bestTrim *)
(*Use SAR approach to trim resolution on VAD scale bits 11-0*)
(* bestTrim now contains the trim that gives the lowest delta*)
