Type "P" code - Indicates charger programming mode is active. This will occur when the charger profile is
being configured.
Type "USB" code - Indicates the USB interface is active, and the USB should not be removed. This will
occur when the charger firmware is being updated.
Solid red - Internal fault condition. Type "F" fault code.
Flashing amber - External fault condition. Type "E" error code.
Flashing green - USB interface is active.
