0005 Description:
0006 Event generated when channel passes one of the four thresholds
0007 in each direction (rising|falling) and a zone change occurs.
0008 The corresponding light zone can be read from
0009 in_illuminance0_zone.

0024 Description:
0025 Specifies the value of threshold that the device is comparing
0026 against for the events enabled by
0027 in_illuminance0_thresh_either_en (0..255), where Y in 0..3.
0028
0029 Note that threshY_falling must be less than or equal to
0030 threshY_raising.
0031
0032 These thresholds correspond to the eight zone-boundary
0033 registers (boundaryY_{low,high}) and define the five light
0034 zones.

0048 Description:
0049 Set the output current for channel out_currentY when in zone
0050 Z (0..255), where Y in 0..2 and Z in 0..4.
0051
0052 These values correspond to the ALS-mapper target registers for
0053 ALS-mapper Y + 1.
0054
0055 Note that out_currentY_raw provides the current for the
0056 current zone.
