Question about AM1808 USB

Hi,

I have a question about AM1808 USB.

Our AM1808 silicon revision is rev2.1 and using USB0.

There are errata "Advisory 2.1.10 USB0 PLL Mean Frequency Can Drift Across Large Temperature Swings".

I have a question about the following workaround of this Advisory:

/////////////////////////////////////////////////////////////////////

One such approach is to look for an absence of USB0 Core interrupts over a specified time window.

This window should be optimized for the expected USB traffic based upon the application.

/////////////////////////////////////////////////////////////////////

How to check USB communication abnormality,

if communication from the host isn't periodically and don't know when host communication will occur?

best regards,

g.f.
