Description
Interrupt Pin. This register identifies which interrupt pin a device uses. Since the USB
uses INTA#, this value is set to 01h.
Description
Minimum Grant. This register specifies the desired settings for how long a burst the
USB needs assuming a clock rate of 33 MHz. The value specifies a period of time in
units of 1/4 microsecond.
Description
Maximum Latency. This register specifies the desired settings for how often the USB
needs access to the PCI bus assuming a clock rate of 33 MHz. The value specifies a
period of time in units of 1/4 microsecond.
