/*
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'.
