USB-KW24D512 system reset will cause USB CDC module reset as well

I'm using USB CDC Driver of USB-KW24D512 Dongle as a virtual com port on Windows OS. I can use Putty to communicate with the USB Dongle.


One requirement for me now is that when the MCU occurs a software reset (for example, set the SYSRESETREQ bit), I would like not to reset USB CDC module. If so, I need to restart the putty to connect with the device again. This is doable for manual configuration, however, that would not be a good way for automation software.


Therefore, is there a way to bypass the USB CDC module reset when a system reset occurs or is there a kind of Reset which only erases the RAM memory?


Thanks for any help.
