Register 16: USB Device Control (USBDEVCTL), offset 0x060
USBDEVCTL is an 8-bit register used for controlling and monitoring the USB VBus line. If the PHY
is suspended, no PHY clock is received and the VBus is not sampled.
USBDEVCTL provides the status information for the current operating mode (host or device) of the
USB controller. If the USB controller is in host mode, this register also indicates if a full- or low-speed
device has been connected.
