26.3.1.3
Offset 04h: HCSPARAMS - Host Controller Structural Parameters
Register
This is a set of fields that are structural parameters: Number of downstream ports, etc.
Some fields in this register are writable when the WRT_RDONLY bit is set. Fields that
are described as “hardwired” are never writable. This register is implemented in the
suspend well to avoid having to reload the parameters following a system sleep state in
which the core power is removed.

DP_N
Debug Port Number: Hardwired to 1h, indicating that
the Debug Port is on the lowest numbered port.
Reserved Reserved.
Port Indicators: This bit indicates whether the ports
P_INDICATOR
support port indicator control. CMI USB 2.0 Controller
does not support Port Indicator LEDs, and this bit is hard
wired to ‘0’.
N_CC
Number of Companion Controllers: This field indicates
the number of companion controllers associated with this
USB 2.0 host controller.
A 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 USB 1.1 host controller(s). Port-ownership
hand-offs are supported. High, Full- and Low-speed
devices are supported on the host controller root ports.
