8.3.2 HPD, AUX, and DDC Switching

HPD, AUX and DDC switching is supported through the HD3SS215. This enables the device to work in multiple application scenarios within multiple electrical standards. The AUXA/B and DDCA/B lines can both be switched to the AUXC port. This feature supports DP++ or AUX only adapters. For HDMI applications, the DDC channels are switched to the DDC_C port only and the AUX channel can remain active or the end user can make it float.
