Description
-
Debug Port Number: This field identifies which of the Host Controller ports is the debug port.
A nonzero value in this field indicates the presence of a debug port. The value in this register
must not be greater than N_PORTS.
-
Port Indicators: This bit indicates whether ports support port indicator control. When this bit is
logic 1, port status and control registers include a read and writable field to control the state of
the port indicator. This bit is set by the AMB3 pin during reset.
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
the 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 the 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.
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.
