This bit can be written to even if USBE is zero or FRZCLK is one. Disabling the USBC (by writing a zero to the USBE bit) does
not reset this bit.
Writing a zero to this bit has no effect.
Writing a one to this bit will send an upstream resume to the host for a remote wakeup.
This bit is cleared when the USBC receives a USB reset or once the upstream resume has been sent.
Writing a zero to this bit will reconnect the device.
Writing a one to this bit will physically detach the device (disconnect internal pull-up resistor from DP and DM).
Writing a zero to this bit has no effect.
Writing a one to this bit will activate the UADD field (USB address).
This bit is cleared when a USB reset is received.
