      Hi ,

       

      I am using CY8C4128LQI-BL543 trying to measure the ECO frequency with a frequency counter. I am using the reference guide for it. unfortunately, there is not reference to how to route the ECO to the GPIO for measurement, although it is mentioned in the reference document that it is needed as part of the Xtal trimming

       

      the reference document is here:

      and the reference for routing is here:
