Index 30h-3Bh
Index 3Ch
This register identifies the system interrupt controllers to which the device’s interrupt pin is connected. The value of this register is used
by device drivers and has no direct meaning to USB.
Index 3Dh
This register selects which interrupt pin the device uses. USB uses INTA# after reset. INTB#, INTC# or INTD# can be selected by writ-
ing 2, 3 or 4, respectively.
Index 3Eh
This register specifies how long a burst is needed by the USB, assuming a clock rate of 33 MHz. The value in this register specifies a
period of time in units of 1/4 microsecond.
Index 3Fh
This register specifies how often (in units of 1/4 microsecond) the USB needs access to the PCI bus assuming a clock rate of 33 MHz.
Index 40h-43h
Used for internal debug and test purposes only.
