Table 1. Register Map
If the INTE bit is set to 1, then the INTS status bit is asserted if the light intensity exceeds either upper or lower threshold
limits (as specified by registers 0x05 and 0x06, respectively) for a period longer than that defined by the Threshold
Timer register (0x07). This bit resets to 0 after the host reads this register. See Table 2.
This bit is also reflected on the INT pin. When the INTS bit is set, the INT pin is asserted low, and when the INTS bit is
set to 0, the INT pin is pulled high by an external resistor.
Once this bit is set, it can be cleared either by reading the Interrupt Status register 0x00 or by writing a 0 to the Interrupt
Enable register 0x01.
