The reason we have both operations is partly that some hardware can configure the ratio but not do TDM and partly that setting TDM slots forces us to configure the slot size depending on the current stream configuration while just setting the ratio means we can just fix the configuration once. I'd say it's just a user error to try to do both simultaneously.
