Has anyone been able to get USB working on a TM4C129ENCZAD running with 320 MHz PLL? In the TIVAWare USB Library User's Guide, it even gives the code for configuring a 320 MHz PLL:
The following is an example of configuring the USB
library to operate when the application is using a 320 MHz PLL.
Example: Using 320MHz PLL setting
uint32_t ui32PLLFrequency;
ui32PLLFrequency = 320000000;
//
// Inform the USB library that the system is running using a 320 MHz PLL.
//
USBDCDFeatureSet(0, USBLIB_FEATURE_USBPLL, &ui32PLLFrequency);
But if you open the source for USBDCDFeatureSet(USBLIB_FEATURE_USBPLL), the passed in value MUST be divisible by 60 MHz. So there seems to be a discrepancy between the documentation and the source code. So is it even possible for USB to work with 320 MHz PLL?
