*
* 6. At high temperature (TA > +85°C), the digital supply current (IVD)
* may be excessive (up to an additional 200 μA), which is most easily
* observed while the part is being held in reset (RESET# active low).
*
* Root Cause: At initial powerup of the device, the logic that drives
* the clock and write enable to the S/PDIF SRC RAMs is not properly
* initialized.
* Certain random patterns will cause a steady leakage current in those
* RAM cells. The issue will resolve once the SRCs are used (turned on).
*
* Workaround: The following verb sequence briefly turns on the S/PDIF SRC
* blocks, which will alleviate the issue.
