Are there any matters of concern about C6745 RSV4 pin unconnected?

Hi Champs,

According to the latest C6745 datasheet SPRS377F, RSV4 pin description has changed as follows.

  - SPRS377F Page-6, Revision History

    Updated/Changed RSV4 DESCRIPTION from "...This pin may be tied high or low."
    to "...For proper device operation, this pin must be tied low or to CVDD."

However, one of my customers has already designed and shiped their board on which the RSV4 is unconnected
because the previous pin description was "may", not "must".

So, could you please let me know about any matters of concern about the RSV4 pin configuration that is unconnected?

Thanks in advance for your cooperation.

Regards,
