Comparator Interrupt
The ADP5588 allows the user to trigger an interrupt based on
the light sensor comparator inputs. Changes in lighting condition
that cause the settings of L2 and L3 to jump from one mode to
another (dark, office, outdoor) set the comparator interrupt bits
in Register 0x02. If the comparator interrupt enable bits are set,
the interrupt pin is asserted every time the comparator
interrupt bits are set. The comparator interrupt flag can be
cleared only by writing a 1 to it.
