203 *
204 * Root Cause: At initial powerup of the device, the logic that drives
205 * the clock and write enable to the S/PDIF SRC RAMs is not properly
206 * initialized.
207 * Certain random patterns will cause a steady leakage current in those
208 * RAM cells. The issue will resolve once the SRCs are used (turned on).
