Revision
Indicates the Open HCI Specification revision number implemented by
the Hardware. Host Controller supports 1.1 specification.
(X.Y = XYh)
Reserved. Read/Write 0's
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)
PeriodicListEnable
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.
IsochronousEnable
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.
ControlListEnable
When set this bit enables processing of the Control list.
BulkListEnable
When set this bit enables processing of the Bulk list.
