read only bit. It is set and cleared by the USB hardware.
•Bit 3
– RESUME FLGL Resume Flag
When the USB hardware receives a resume signal from the upstream device it sets this bit.
This bit will stay set until the USB hardware completes the downstream resume signaling. This
bit is a firmware read only bit. It is set and cleared by the USB hardware.
•Bit 2
– RMWUPE: Remote Wakeup Enable
This bit is set if the host enables the hub's remote wakeup feature.
•Bit 1

This bit is set by firmware after a valid SET_CONFIGURATION request is received. It is
cleared by a reset or by a SET_CONFIGURATION with a value of 0.
•Bit 0

This bit is set by firmware after the status phase of a SET_ADDRESS request transaction so
the hub will use the new address starting at the next transaction.
