31.7.33 OTG Status and Control Register (HW_USBCTRL_OTGSC)
Host Controller: A host controller implements one On-The-Go (OTG) Status and Control
register corresponding to Port 0 of the host controller. The OTGSC register has four sections:
OTG Interrupt Enables (Read/Write) OTG Interrupt Status (Read/Write to Clear) OTG
Status Inputs (Read-Only) OTG Controls (Read/Write) The status inputs are debounced
using a 1-ms time constant. Values on the status inputs that do not persist for more than 1
ms will not cause an update of the status input register, or cause an OTG interrupt. See also
USBMODE register. The default value of this register is 0x00000120.

0
Default = 0.
In Host Mode:
Indicates a change has occurred in the port's Current Connect Status. The host/device controller sets this
bit for all changes to the port device connect status, even if system software has not cleared an existing
connect status change. For example, the insertion status changes twice before system software has cleared
the changed condition, hub hardware will be 'setting' an already-set bit (i.e., the bit will remain set). Software
clears this bit by writing a 1 to it.
This field is 0 if Port Power (PP) is 0 in host mode.
In Device Mode:
This bit is undefined in device controller mode.
Current Connect Status.
In Host Mode:
0 = No device is present.
1 = Device is present on port.
Default = 0.
This value reflects the current state of the port, and may not correspond directly to the event that caused
the Connect Status Change bit (Bit 1) to be set.
This field is 0 if Port Power (PP) is 0 in host mode.
In Device Mode:
0 = Not Attached.
1 = Attached.
Default = 0.
A 1 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 0 indicates that the device did not attach successfully or was forcibly disconnected by the software writing
a 0 to the Run bit in the USBCMD register. It does not state the device being disconnected or suspended.
