BITS DESCRIPTION
[31:11] Reserved Reserved. Read/Write 0's
[10] RWCE
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.
[9] RWC
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.’
[8]
INR
InterruptRouting
This bit is used for interrupt routing:
0: Interrupts routed to normal interrupt mechanism (INT).
1: Interrupts routed to SMI.
[7:6] HCFS
HostControllerFunctionalState
This field sets the Host Controller state. The Controller may force a state
change from USB
S USPEND to USB R ESUME after detecting resume
signaling from a downstream port. States are:
00: USB
R ESET
01: U SB R ESUME
10: U SB O PERATIONAL
11: U SB S USPEND
[5]
BLE BulkListEnable
When set this bit enables processing of the Bulk list.
[4]
CLE Control Listenable
When set this bit enables processing of the Control list.
[3]
ISE
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.
[2] PLE
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.
[1:0]
CBR
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)
