Description
-
Periodic Start: After a hardware reset, this field is cleared. It is then set by the HCD during the
Host Controller initialization. The value is roughly calculated as 10 % of HcFmInterval. A typical
value is 3E67h. When HcFmRemaining reaches the value specified, processing of the periodic lists
have priority over control or bulk processing. The Host Controller, therefore, starts processing the
interrupt list after completing the current control or bulk transaction that is in progress.
This register has a 14-bit programmable value that determines when is the earliest time
for the Host Controller to start processing the periodic list. For bit allocation, see
This register contains an 11-bit value used by the Host Controller to determine whether to
commit to the transfer of a maximum of 8-byte low-speed packet before EOF. Neither the
Host Controller nor the HCD can change this value. For bit allocation, see
