ICD settings have high impact on audio performance (eg: Dynamic Range, THD, Cross talk etc.) Therefore,
appropriate ICD settings must be used. By default device has ICD settings for BD mode. If used in AD mode,
then update these registers before coming out of all channel shutdown. Contact factory for AD Mode ICD
settings.
