Hi,
the triangle, in front of value EE (in the memory window), says that the value is not updated/refreshed/known. The reason is the COP and communication with PC. The COP is normally not debuggable because it is an reset and the communication between debugger and MCU is lost. The best way is to debug and set behavior of the CPU at the beginning of the project and then implement it into a project. Next possible debugging is to signalize COP by diodes or use UART (SCI) for sending messages to a PC. I usually use diodes as presented below (tested on TRKS12ZVL). If you want to see correct behavior of the COP the most suitable way is to disconnect BDM from the board and start the MCU by power on or reset button.
If my explaation is not clear do not hesitate to contact me again.
