Hello,

We do not have any example of measure the transaction time between the two cores. However, you can create an example code using the MU module. With the interrupts and a pre-programmed timer, you could measure the exact transaction time between the cores. Unfortunately, this is our pf our scope of support. If you want help in the develop the code, I suggest you contact professional service support.

Best regards,

Diego.
