Description
-
Isochronous Scheduling Threshold: Default = implementation
dependent. This field indicates, relative to the current position of the
executing Host Controller, where software can reliably update the
isochronous schedule. When IST[3] is logic 0, the value of the least
significant three bits indicates the number of micro frames a Host
Controller can hold a set of isochronous data structures, one or
more, before flushing the state. When IST[3] is logic 1, the host
software assumes the Host Controller may cache an isochronous
data structure for an entire frame.
