This field is set according to the controller speed mode. This field shall only be used in device mode.
This bit is set when the VBus line level is high, even if USBE is zero.
This bit is cleared when the VBus line level is low, 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, event if USBE is zero.
This bit is set when the USBSTASET.VBUSRQS bit is written to one.
This bit is cleared when the USBSTACLR.VBUSRQC bit is written to one or when a VBus error occurs and VBUSHWC is zero.
1: The USB_VBOF output pin is driven high to enable the VBUS power supply generation.
0: The USB_VBOF output pin is driven low to disable the VBUS power supply generation.
This bit shall only be used in host mode.
This bit is set when a time-out error (more than 200ms) has been detected after a suspend. This triggers a USB interrupt if
STOE is one.
This bit is cleared when the UBSTACLR.STOIC bit is written to one.
This bit shall only be used in host mode.
