module will issue interrupts. ITC contains the maximum interrupt interval measured in microframes. Valid
values are shown below.

on the use of this bit is described in
Setup tripwire. This is a non-EHCI bit. Used as a semaphore when the 8 bytes of setup data read extracted
from a QH by the DCD. If the setup lockout mode is off (See USBMODE) then there exists a hazard when
new setup data arrives and the DCD is copying setup from the QH for a previous setup packet. This bit is
set and cleared by software and will be cleared by hardware when a hazard exists. More information on the
use of this bit is described in
Reserved, should be cleared.
Asynchronous schedule park mode enable. This bit defaults to a 1 and is R/W. Software uses this bit to
enable or disable park mode.
