This bit is cleared when the USB generic clock is not usable.
This bit is set when the USB generic clock (that should be 48 Mhz) is usable.
This field is set according to the controller speed mode.
SPEED
This bit is cleared when the VBUS line level is low, even if USBE is zero.
This bit is set when the VBUS line level is high, even if USBE is zero.
This bit can be used in device mode to monitor the USB bus connection state of the application.
This bit is cleared when the USB_ID level is low, even if USBE is zero.
This bit is set when the USB_ID level is high, even if USBE is zero.
0: The USB_VBOF output pin is driven low to disable the VBUS power supply generation.
1: The USB_VBOF output pin is driven high to enable the VBUS power supply generation.
This bit is cleared when USBSTACLR.VBUSRQC is written to one or when a VBUS error occurs while VBUSHWC is zero.
This bit is set when USBSTASET.VBUSRQS is written to one.
This bit should only be used in host mode.
