HS USB PCI host controller
11.3.8 PORTSC registers 1, 2
The Port Status and Control (PORTSC) register is in the auxiliary power well. It is only
reset by hardware when the auxiliary power is initially applied or in response to a host
controller reset. The initial conditions of a port are:
No device connected
Port disabled
If the port has power control, software cannot change the state of the port until it sets port
power bits. Software must not attempt to change the state of the port until power is stable
on the port; maximum delay is 20 ms from the transition. For bit allocation, see Table 114.
[1]
The reserved bits must always be written with the reset value.

Congure Flag: The host software sets this bit as the last action in its process of conguring
the host controller. This bit controls the default port-routing control logic.
0 — Port routing control logic default-routes each port to an implementation dependent classic
host controller.
1 — Port routing control logic default-routes all ports to this host controller.
