establish a policy about which ports are to be used for wake events. Bit positions 1-4 in
the mask correspond to a physical port implemented on the current EHCI controller. A
‘1’ in a bit position indicates that a device connected below the port may be enabled as
a wake-up device, and the port may be enabled for disconnect/connect or over-current
events as wake-up events. This is an information-only mask register. The bits in this
register do not affect the actual operation of the EHCI host controller. The system-
specific policy may be established by BIOS initializing this register to a system-specific
value. System software uses the information in this register when enabling devices and
ports for remote wake-up.

These bits are reserved for future use and should read as

Each decimal value change to this register corresponds to 16
high-speed bit times. The SOF cycle time (number of SOF
counter clock periods to generate a SOF micro-frame length)
is equal to 59488 + value in this field. The default value is
decimal 32 (20h), which gives a SOF cycle time of 60000.
