Description
reserved
Scheduling Overrun Count: The bit is incremented on each scheduling
overrun error. It is initialized to 00b and wraps around at 11b. It must be
incremented when a scheduling overrun is detected, even if the SO bit in
HcInterruptStatus is already set. This is used by the HCD to monitor any
persistent scheduling problems.
reserved
Ownership Change Request: This bit is set by an OS HCD to request a
change of control of the Host Controller. When set, the Host Controller
must set the OC (Ownership Change) field in HcInterruptStatus. After the
changeover, this bit is cleared and remains so until the next request from
the OS HCD.
Bulk List Filled: This bit is used to indicate whether there are any
Transfer Descriptors (TDs) on the bulk list. It is set by the HCD whenever
it adds a TD to an ED in the bulk list. When the Host Controller begins to
process the head of the bulk list, it checks Bulk-Filled (BF). If BLF (Bulk
List Filled) is logic 0, the Host Controller does not need to process the
bulk list. If BLF is logic 1, the Host Controller must start processing the
bulk list and set BF to logic 0. If the Host Controller finds a TD on the list,
then the Host Controller must set BLF to logic 1, causing the bulk list
processing to continue. If no TD is found on the bulk list, and if the HCD
does not set BLF, then BLF is still logic 0 when the Host Controller
completes processing the bulk list and the bulk list processing stops.
