I am working with MK66 MCU with our own customized board .,
1.) I am using SDK_2.0_MK66FN2M0xxx18 stack , In that stack they are using USB1 with high speed (USB-HS) , In our board I am using USB0 and running in full speed , Can anyone tell me what are the changes need to be change in stack to switch from USB1 to USB0 .
2.) Can I generate core clock frequency (ex 180 MHZ) by using Internal clock resource without using external clock reference.
