MKL16Z256 - Why are some Peripherals locked out at time to time

MCUXpresso IDE v11.0.0 [Build 2516] [2019-06-05]

Segger j-link Plus



I am attempting to set the COP registers to start, stop and refresh the WatchDog.


While stepping through code, I will attempt to view my MCU's Peripherals, like the SIM, in the Peripherals window or the Memory window.

But the peripheral, or some of its registers will be locked out.


Why is this happening?
