USB Global State Register
Register Name:
Access Type:
This register is used to get and set the device state as specified in Chapter 9 of the USB Serial Bus Specification, Rev.2.0.
• FADDEN: Function Address Enable
Read:
0 = Device is not in address state.
1 = Device is in address state.
Write:
0 = No effect, only a reset can bring back a device to the default state.
1 = Set device in address state. This occurs after a successful Set Address request. Beforehand, the USB_FADDR register
must have been initialized with Set Address parameters. Set Address must complete the Status Stage before setting FAD-
DEN. Please refer to chapter 9 of the Universal Serial Bus Specification, Rev. 2.0 to get more details.
• CONFG: Configured
Read:
0 = Device is not in configured state.
1 = Device is in configured state.
Write:
0 = Set device in a nonconfigured state
1 = Set device in configured state.
The device is set in configured state when it is in address state and receives a successful Set Configuration request.
Please refer to Chapter 9 of the Universal Serial Bus Specification, Rev. 2.0 to get more details.
• ESR: Enable Send Resume
0 = Disable the Remote Wake Up sequence.
1 = Remote Wake Up can be processed and the pin send_resume is enabled.
• RSMINPR: A Resume Has Been Sent to the Host
Read:
0 = No effect.
1 = A Resume has been received from the host during Remote Wake Up feature.
• RMWUPE: Remote Wake Up Enable
0 = Must be cleared after receiving any HOST packet or SOF interrupt.
1 = Enables the K-state on the USB cable if ESR is enabled.
