Error in ProcessorExpert's Templates concerning MK20DN512Z

It seems that when using the USB-Stack (CDC-Device) the interrupt enable routines in the generated usb1.c are using the wrong NVIC-Registers:

Hello,

There is released a new solution of USB components (fsl_usb_device_hid_class, fsl_usb_device_msd_class, fsl_usb_framework, fsl_usb_descriptors) that is available in KDS 2.0.0 (with installed Kinetis SDK 1.1.0 Eclipse Update).

If you want to start a development of an application based on fsl_usb_.... components, you can use the Processor Expert Kinetis SDK USB Stack Integration User Guide that is available as a part of the help.

You can open the guide by the following way in KDS 2.0.0 (you must have KSDK 1.1.0 Eclipse Update installed):

- Open Component Library window and find fsl_usb_descriptors component.

- Open the context menu of this component (click by right button of the mouse) and select Help on Component item.

- In the Help window, open the fsl_usb_descriptions page

- The fsl_usb_descriptors help page (General Info tab) contains link to the user guide "USB stack Processor Expert integration documentation" at the bottom of the page.

Best Regards,

Marek Neuzil
