• SPDCONF: Mode Configuration
This field contains the peripheral speed:
• RMWKUP: Remote Wake-Up
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 UOTGHS receives a USB reset or once the upstream resume has been sent.
• DETACH: Detach
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.
• ADDEN: Address Enable
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.
• UADD: USB Address
This field contains the device address.
This field is cleared when a USB reset is received.

Description
The peripheral starts in full-speed mode and performs a high-speed reset to switch to the
high-speed mode if the host is high-speed capable.
For a better consumption, if high-speed is not needed.
Forced high speed.
The peripheral remains in full-speed mode whatever the host speed capability.
