+ * @def VL6180x_HAVE_DMAX_RANGING
+ * @brief Enable DMax calculation for ranging applications.
+ *  
+ * When set to 1, __Dmax__ is returned by API typically when  @a VL6180x_RangePollMeasurement() high level
+ * function is called (this is returned in @a VL6180x_RangeData_t structure).
+ * __Dmax__ is an estimation of the maximum distance (in mm) the product can report a valid distance of a 17% target for 
+ * the current ambient light conditions (__Dmax__ decreases when ambient light increases). __Dmax__ should be used only
+ * when the product is not able to return a valid distance (no object or object is too far from the ranging sensor).
+ * Typically, this is done by checking the __errorStatus__ field of the @a VL6180x_RangeData_t structure returned by 
+ * the @a VL6180x_RangePollMeasurement() function.
+ * You may refer to ::RangeError_u to get full list of supported error codes.
+ * @warning Dmax is estimated for a 17% grey target. If the real target has a reflectance lower than 17%, report Dmax could be over-estimated

+ *  
+ * In specific conditions, when targeting a mirror or a very reflective metal, a __wrap around__ effect can occur internally to the
+ * ranging product which results in returning a wrong distance (under-estimated). Goal of the WAF is to detect this wrap arround effect
+ * and to filter it by returning a non-valid distance : __errorStatus__ set to 16 (see ::RangeError_u)
+ * @warning Wrap-around filter can not be used when device is running in continuous mode 
+ * 
+ * @li 0 : Filter is not supported, no filtering code is included in API
+ * @li 1 : Filter is supported and active by default
+ * @li -1 : Filter is supported but is not active by default @a VL6180x_FilterSetState() can turn it on and off at any time
