Need help on XA-S3 serie controller. Heavy tech question.

Hello everyone,

Regarding UART function of this type of controller.

I've noticed that processing time of incoming stop bit (from communication partner) deviates within 500us range.

Moreover, I would not say that it processes some sequent/parallel tasks at the moment. It's at idle state.

In other words, the controller responds always at different time, thus causes issues in the bus.

Questions:

-How do I treat this misbehaving?

Perhaps someone faced with something similar. Different controller or so.
