Zeroize Red and Black memories of the SCC. This will start the Zeroizing process. The routine will return when the memories have zeroized or failed to do so. The driver will poll waiting for this to occur, so this routine must not be called from interrupt level. Some future version of driver may elect instead to sleep.
