Note
1. 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 8.2 "Boot Strap Signals".
2. The second HDMI interface is only available if LVDS is disabled.
3. The conga-TCA3 does not natively support TMDS. A DP++ to TMDS converter (e.g. PTN3360D) needs to be implemented.
