Hi when used as a slave device it would seem the SGPIO has no mechanism to synchronize to the master device word / frame / LR clock. A bit of an oversight or have I missed something in the data sheet?

I have tried using a clock qualifier to gate the incoming clock to pull the data in line. This has mixed success and resync can take many frames.

Is there a way to reset the POS counter from an input pin perhaps, much like a standard external SPI peripheral?
