31.7.32 Port Status and Control 1 Register (HW_USBCTRL_PORTSC1)
Host Controller: A host controller must implement one to eight port registers. The number
of port registers implemented by a particular instantiation of a host controller is documented
in the HCSPARAMs register and is fixed at 1 in this implementation. Software uses this
information as an input parameter to determine how many ports need service. This register
is only reset when power is initially applied or in response to a controller reset. The 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
1. Device Controller: A device controller must implement only port register 1 and it does
not support power control. Port control in device mode is only used for status port reset,
suspend, and current connect status. It is also used to initiate test mode or force signaling
and allows software to put the PHY into low power suspend mode and disable the PHY
clock. * Default Value: 00010000000000000000XX0000000000b (Host mode)
00010000000000000001XX0000000100b (Device mode) X = Unknown

Parallel Transceiver Width.
This bit is always 1, indicating an 16-bit (30-MHz) UTMI interface.
Port Speed.
This register field indicates the speed at which the port is operating. For high-speed mode operation in the
host controller and high-speed/fullspeed operation in the device controller, the port routing steers data to
the protocol engine.
