Wakeup Interrupt Controller

Hi, we are seeing subtle timing differences in code execution between when we have a debugger attached or not (same build of code). 

Does the nRF52832 implement the optional wakeup interrupt controller https://developer.arm.com/docs/dui0553/a/the-cortex-m4-processor/power-management/the-optional-wakeup-interrupt-controller as this may explain the issues we see?
