Note:
Text in red indicates signals that are not used on the display adapters
LCD-014-x and LCD-017-x. They are included in the PDI
specification to provide more functions for a customer designed
display adapter or front panel (e.g. an integrated USB connector or
power switch). Please refer to the Carrier Board section within the
hardware manual of your phyCARD or phyCORE module to get
information how to use these signals.
