 * 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.
