1: The low-speed mode is active.
0: The full-speed mode is active.
This bit can be written even if USBE is zero or FRZCLK is one. Disabling the USBB (by writing a zero to the USBE bit) does not
reset this bit.
Writing a one to this bit will send an upstream resume to the host for a remote wake-up.
Writing a zero to this bit has no effect.
This bit is cleared when the USBB receive a USB reset or once the upstream resume has been sent.
Writing a one to this bit will physically detach the device (disconnect internal pull-up resistor from D+ and D-).
Writing a zero to this bit will reconnect the device.
Writing a one to this bit will activate the UADD field (USB address).
Writing a zero to this bit has no effect.
This bit is cleared when a USB reset is received.
This field contains the device address.
This field is cleared when a USB reset is received.
