6 | Event generated when channel passes one of the four thresholds | |
7 | in each direction (rising|falling) and a zone change occurs. | |
8 | The corresponding light zone can be read from | |
9 | in_illuminance0_zone. | |

24 | Description: | |
25 | Specifies the value of threshold that the device is comparing | |
26 | against for the events enabled by | |
27 | in_illuminance0_thresh_either_en (0..255), where Y in 0..3. | |
28 | ||
29 | Note that threshY_falling must be less than or equal to | |
30 | threshY_raising. | |
31 | ||
32 | These thresholds correspond to the eight zone-boundary | |
79e9b4e6 | 33 | registers (boundaryY_{low,high}) and define the five light |

34 | zones. |
