MSPM0G3507: Determine QEI Zero Event Trigger

Tool/software:

Hello,

Is there a way of determining whether a QEI zero event was triggered by the Index Input edge versus by the counter reaching the load value for the 3-Input QEI timer mode?

I could just read Index input GPIO input register in the QEI ISR after zero even detection but there's a chance that the index input might not still be valid at the point if the ISR were delayed.

I wondering if there's some way of distinguishing index triggered zero event versus the counter reaching the load value using the timer itself.

Thanks for your support,

Ben
