10.3.4.13 Configure Flag Register (CONFIGFLAG)
This EHCI register is not used in this implementation. A read from this register returns a constant of a
0x0000_0001 to indicate that all port routings default to this host controller.
Address: 0xFC0B_0180 (CONFIGFLAG)

10.3.4.14 Port Status and Control Registers (PORTSCn)
The USB module contains a single PORTSC register. This register only resets when power is initially
applied or in response to a controller reset. Initial conditions of a port are:
• No device connected
• Port disabled
If the port has port power control, this state remains until software applies power to the port by setting port
power to one.
For the USB OTG module in device mode, the USB OTG controller does not support power control. Port
control in device mode is used only for status port reset, suspend, and current connect status. It is also used
to initiate test mode or force signaling, and allows software to place the PHY into low-power suspend
mode and disable the PHY clock.
