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 7.5 of this user’s guide.
The Digital Display Interface (DDI) signals are multiplexed with HDMI, DisplayPort (DP) and SDVO. The signals for these interfaces are routed
to the DDI interface of the COM Express connector. The SDVO interface is however not supported on the conga-TCA.
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.
