Powering the USB and RTC Module on TMS320VC5509A/07/06/03 devices.

If I don`t want to use the USB and RTC module on the C5509A/07/06/03 devices , would it matter if I did not power their corresponding power pins USBVdd and RDVdd RCVdd? Will this affect the proper functioning of other modules.
Answer: Even if the RTC or USB module are not used, both modules have to be powered. For RTC and USB module, RDVdd RCVdd and USBVdd pins have to be connected to their corresponding power supplies and ground pins.  C5509A/07/06/03 data manuals have the recommended connections.
