The RGBC interrupt threshold registers provides the values to be used as the high and low trigger points for
the comparison function for interrupt generation. If the value generated by the clear channel crosses below the
lower threshold specified, or above the higher threshold, an interrupt is asserted on the interrupt pin.
The proximity interrupt threshold registers provide the values to be used as the high and low trigger points for
the comparison function for interrupt generation. If the value generated by proximity channel crosses below the
lower threshold specified, or above the higher threshold, an interrupt is signaled to the host processor.
