It is permissable to ground the DVDDEMIF supply pins if the following conditions are all met:

  • At least one DVDDEMIF package ball is grounded. The others must be either floating or grounded.
  • All signal pins that use DVDDEMIF as their I/O supply voltage (all of the pins listed in the External Memory Interface Terminal Functions table located in the TMS320C5505 Fixed-Point Digital Signal Processor Data Manual and the TMS320C5515 Fixed-Point Digital Signal Processor Data Manual), regardless of multiplexing options, are either:

  • All grounded
  • All floating (not driven by any external source)
  • Any combination of grounded or floating

    •
