Comments
No active state.
Waiting for measurement command.
Switch measurement mode automatically by illuminance.
Start measurement at 1lx resolution.
Measurement Time is typically 120ms.
Start measurement at 8lx resolution.
Measurement Time is typically 16ms.

We recommend to use H-Resolution Mode.
Measurement time (integration time) of H-Resolution Mode is so long that some kind of noise (including in 50Hz / 60Hz
noise) is rejected. And H-Resolution Mode is 1 lx resolution so that it is suitable for darkness (less than 20 lx)
Auto-Resolution mode selects measurement mode automatically. It is determined after 16ms (typ.) passes from
measurement start. If BH1721FVC judges that current illuminance is more than 4000 lx, then Data is output at L-resolution
mode, else Data is output after 120ms(typ.) from measurement start at H-resolution mode. Please refer below flow chart.
