ALS_THRES Register (0x97 / 0x98 / 0x99 / 0x9A)
The ALS_THRES_UP and ALS_THRES_LOW registers determines the upper and lower limit of the interrupt threshold
value respectively. These two values form a range and the interrupt function compares if the measurement value in
ALS_DATA registers is inside or outside the range. The interrupt function is active if the measurement data is outside the
range defined by the upper and lower limits. The data format for ALS_THRES must be the same as ALS_DATA registers.
