INTERRUTP Register (0x8F) (Read Only)
The INTERRUPT register controls the operation of the interrupt pin and functions. When the Interrupt Mode is set to 00,
the INT output pin 2 is inactive / disabled and will not trigger any interrupt. However at this condition, the
ALS_PS_STATUS register will still be updated.
Note that when this register is to be set with values other than its default values, it should be set before device is in Active
mode.
