;  FUNCTION NAME: CSD2X_1_UpdateSensorBaseline(BYTE bSensorNum)
;
;  DESCRIPTION:
;      Update baseline for one sensor. The algorithm is as follows:
;        If difference count is negative baseline become raw count
;        If difference count is above noise threshold do not update
;        Else difference count is positive and within noise threshold so
;        difference is halved and added to the bucket. When the bucket
;        reaches the threshold the baseline increments and the bucket resets
;-----------------------------------------------------------------------------
;  STACK USAGE: 0 BYTES
;
;  ARGUMENTS:
;      A => Sensor Number
;
;  RETURNS:
;      Nothing
;
;  SIDE EFFECTS:
;    The A and X registers may be modified by this or future implementations
;    of this function.  The same is true for all RAM page pointer registers in
;    the Large Memory Model.  When necessary, it is the calling function's
;    responsibility to perserve their values across calls to fastcall16
;    functions.
