TMS320DM8168 HDMI query

Hi Folks,

I Have a query pertaining to below.

I would like to know, if my understanding of the above statement is correct, it means that regardless of using HDMI, these VDDA_HDMI pins should be connected to 1.0V power supply source?

Is this correct? If not, what is the explanation for this?

    Srijan,

    Refer to the DM816x DataSheet for how to handle unused pins:

    5.6 How to Handle Unused Pins
    When device signal pins are unused in the system, they can be left unconnected unless otherwise instructed in the Terminal Functions tables. For unused input pins, the internal pull resistor should be enabled, or an external pull resistor should be used, to prevent floating inputs. All supply pins must always be connected to the correct voltage, even when their associated signal pins are unused, as instructed in the Terminal Functions tables in Section 3.2.
