66AK2H12/06 USB3SS scratchpad

Other Parts Discussed in Thread: 66AK2H12

Hello,
66AK2H12/06 has USB3SS.

- Can I think it is same as Intel xHCI controller?

- Can I give us any support documents about scratchpad and USB3SS?

Background:
I would like to understand the detail of scratchpad in USB3SS.
But, there is no detail in UG.
Instead, Reference Documentation specifies eXtensible Host Controller Interface Spec.

Best regards, RY

RY,

Yes, running in Host mode, the controller is compatible to Intel's xHC. Since this USB3SS supports Dual-role mode and Device modes too, other than the Host mode. It has more features other than the xHCI defined.

Regarding the scatchpad buffers, they are typically used for Hibernation operation for saving and restoring states of the USB3SS.

Regards!
Wen
