Note
Some signals have special functionality during the reset process. They may bootstrap some basic important functions of the module. For more
information refer to section 8.5 of this user’s guide.
The Digital Display Interface (DDI) signals are multiplexed with HDMI and DisplayPort (DP). The signals for these interfaces are routed to the
DDI interface of the COM Express connector. Refer to the HDMI and DisplayPort signal description tables in this section for information about
the signals routed to the DDI interface of the COM Express connector.
