DRV8424E: The selection of decay mode

Hi team,

Here's an issue from the customer may need your help:

There're 6 decay modes of DRV8424, how to select them? Could you help elaborate the application scenario respectively?

1. Rise/Smart Tune Dynamic Decay + Fall/Smart Tune Dynamic Decay

2. Rise/Smart Tune Ripple Control + Fall/Smart Tune Ripple Control

3. 30% faster rise/mix decay + 30% faster fall/mix decay

4. Rise/slow decay + fall/mix decay 30% faster

5. 60% faster rise/mix decay + 60% faster fall/mix decay

6. Rise/slow decay + fall/slow decay

Thanks and regards,

Cherry
