FORCE_RD 2
1: Forces a read of the light sensor; reset by the internal state machine after conversion is complete and
L2_OUT and L3_OUT are valid.
1
L3_EN 1 1: Enables the L3 comparator for Sensor 1 input.
0: Disables the L3 comparator for Sensor 1 input.
L2_EN 0 1: Enables the L2 comparator for Sensor 1 input.
0: Disables the L2 comparator for Sensor 1 input.
Note that the L3 comparator has priority over the L2 comparator.
1
When the software forces a conversion, the state machine clears the forced bit after the conversion is done and the proper registers have been updated.
