for the VL supply
LED is illuminated when the +3.3 V supply is on (+3.3V is derived from the +5V supply by an on-board
regulator)
LED is illuminated when the +5 V supply is on
LED is illuminated when the VL supply is on (either by the onboard +3.3 V, +5 V or external supply)
LED is illuminated when the CS8416 reports a Receiver Error. See the CS8416 datasheet for a full
description of the error reporting functionality.
