/*

The HcRhPortStatus[1:NDP] register is used to control and report port events on a per-port
|
|
basis. NumberDownstreamPorts represents the number of HcRhPortStatus registers that are
|
|
implemented in hardware. The lower word is used to reflect the port status, whereas the upper
|
|
word reflects the status change bits. Some status bits are implemented with special write behavior
|
|
(see below). If a transaction (token through handshake) is in progress when a write to change
|
|
port status occurs, the resulting port status change must be postponed until the transaction
|
|
completes. Reserved bits should always be written '0'.
