Description:
If the Application's code segment CRC is not equal to the corresponding Application's baseline code segment CRC, CS shall increment the Application Code Segment CRC Miscompare Counter and send an event message.

Was not able to generate a miscompare when reloading a different version of the reqval_app. Loaded reqval_v500 which should have incremented the following error counter: AppCSErrCounter and also generated an event

20220324 - Likely resolution will be to verify via "analysis", aka unit test if reloading an app can not cause the miscompare. Future work might support getting the module address, use MM to "corrupt" the memory to cause the miscompare.
