Universal Serial Bus Interface
24.6.3.14 On-The-Go Status and Control (OTGSC), Non-EHCI
This register is not defined in the EHCI specification. The USB OTG module implements one On-The-Go
(OTG) Status and Control register corresponding to Port 0.
The OTGSC register has four sections:
The status inputs are de-bounced using a 1 msec time constant. Values on the status inputs that do not
persist for more than 1 msec will not cause an update of the Status inputs, or cause and OTG interrupt.

Connect Change Status.
In host mode, this bit indicates a change has occurred in the port’s Current Connect Status. the controller sets this bit
for all changes to the port device connect status, even if the system software has not cleared an existing connect status
change. For example, the insertion status changes twice before the system software has cleared the changed condition,
hub hardware will be ‘setting’ an already-set bit (that is—the bit will remain set). The software clears this bit by writing
a one to it.
1 Connect Status has changed.
0 No change
This field is zero if Port Power(PP) is zero.
In device mode, this bit is undefined.
Current Connect Status.
In host mode:
1 Device is present.
0 No device present.
This field is zero if Port Power(PP) is zero in host mode.
In device mode:
1 Attached
0 Not attached
A one indicates that the device successfully attached and is operating in either high-speed or full-speed as indicated
by the High Speed Port bit in this register. A zero indicates that the device did not attach successfully or was forcibly
disconnected by the software writing a zero to the Run bit in the USBCMD register. It does not state the device being
disconnected or suspended.
