KDS Debugger Backdoor Key (PEmicro)

[guitardenver]

I'm using KDS 3.2.0 with a PEmicro multilink and a MK22FN512 MCU.

How do I set up the debugger to use the backdoor access key to unsecure the device without a mass erase? Is there a command I can pass in or a setting i'm missing in KDS?

Thanks,

Alice,

No, I can use the backdoor, I just wanted a way for PEMicro debugger to be able to use the backdoor key to unsecure the device without a mass erase. I do not see anything about the backdoor key in the KDS debugger settings. I know USBDM has an option to use the backdoor key in their standalone programmer.
