How to measure the resources (run time / memory consumed) by having part of the code block in external memory encrypted (while using OTFDEC in L5 controller).

[VNara.1]

I am using STM32L562VE controller. I have configured OTFDEC with a portion of my code encrypted. Is there any way with which I can measure the run time and memory consumed promptly eventhough the code switches back and forth between internal flash and encrypted external flash code blocks ?
