I am using KDS 3.0.0 with SDK 1.3.0 and Processor Expert on Windows 10 for MK20DX256VLK10 processor.
I am now trying to set the protection and security functions for this device but in the PE window the button to enable the Flash Configuration Field is always greyed out so I cannot enable or configure protection or security.
See screengrab below.
Is there something else I need to do in order to be able to set the security options with the KDS environment?
And below is the Flash Memory Organisation window (I have the EEPROM and DFlash configured and working).
