- * Description:

- * Input Parameters:
- *   None
- *
- * Returned Value.
- *   On success, this function will not return (STANDBY mode can only be
- *   terminated with a reset event).  Otherwise, STANDBY mode did not occur
- *   and a negated errno value is returned to indicate the cause of the
- *   failure.
