DESCRIPTION
Reserved. Read/Write 0's
RemoteWakeupConnectedEnable
If a remote wakeup signal is supported, this bit enables that operation.
Since there is no remote wakeup signal supported, this bit is ignored.
RemoteWakeupConnected
This bit indicated whether the HC supports a remote wakeup signal. This
implementation does not support any such signal. The bit is hard-coded to
‘0.’
InterruptRouting
This bit is used for interrupt routing:
0: Interrupts routed to normal interrupt mechanism (INT).
1: Interrupts routed to SMI.
HostControllerFunctionalState
This field sets the Host Controller state. The Controller may force a state
change from USB SUSPEND to USB RESUME after detecting resume
signaling from a downstream port. States are:
00: USB RESET
01: USBRESUME
10: USBOPERATIONAL
11: USBSUSPEND
BulkListEnable
When set this bit enables processing of the Bulk list.
Control Listenable
When set this bit enables processing of the Control list.
Isochronous Enable
When clear, this bit disables the Isochronous List when the Periodic List is
enabled (so Interrupt EDs may be serviced). While processing the
Periodic List, the Host Controller will check this bit when it finds an
isochronous ED.
Periodic Listenable
When set, this bit enables processing of the Periodic (interrupt and
isochronous) list. The Host Controller checks this bit prior to attempting
any periodic transfers in a frame.
ControlBulkServiceRatio
Specifies the number of Control Endpoints serviced for every Bulk
Endpoint. Encoding is N-1 where N is the number of Control Endpoints
(i.e. ‘00’ = 1 Control Endpoint; ‘11’ = 3 Control Endpoints)
