Description
Number of Companion Controller: This field indicates the number of
companion controllers associated with this Hi-Speed USB Host
Controller. A value of zero in this field indicates there are no companion
Host Controllers. Port-ownership hand-off is not supported. Only
high-speed devices are supported on the Host Controller root ports. A
value larger than zero in this field indicates there are companion Original
USB Host Controller(s). Port-ownership hand-offs are supported.
Number of Ports per Companion Controller: This field indicates the
number of ports supported per companion Host Controller. It is used to
indicate the port routing configuration to system software. For example, if
N_PORTS has a value of 6 and N_CC has a value of 2, then N_PCC can
have a value of 3. The convention is that the first N_PCC ports are
assumed to be routed to companion controller 1, the next N_PCC ports
to companion controller 2, and so on. In the previous example, N_PCC
could have been 4, in which case the first four are routed to companion
controller 1 and the last two are routed to companion controller 2.
The number in this field must be consistent with N_PORTS and N_CC.
Port Routing Rules: This field indicates the method used to map ports
to companion controllers.
0 — The first N_PCC ports are routed to the lowest numbered function
companion Host Controller, the next N_PCC ports are routed to the next
lowest function companion controller, and so on.
1 — The port routing is explicitly enumerated by the first N_PORTS
elements of the HCSP-PORTROUTE array.

Port Power Control: This field indicates whether the Host Controller
implementation includes port power control. Logic 1 indicates the port
has port power switches. Logic 0 indicates the port does not have port
power switches. The value of this field affects the functionality of the Port
Power field in each port status and control register.
N_Ports: This field specifies the number of physical downstream ports
implemented on this Host Controller. The value of this field determines
how many port registers are addressable in the operational register
space. Valid values are in the range of 1h to Fh. Logic 0 in this field is
undefined.
