Function
Interrupt Pin Register. This register identifies which interrupt pin a device uses. Since the
USB Host Controller uses INTA, this register is set to 01H.
Function
PCI Min_Gnt. This register specifies how long of a burst the USB Host Controller needs
assuming a clock rate of 33 MHz. The value specifies a period of time in units of 1/4 micro-
second.
Function
PCI Max. Latency. This register specifies how often the USB Host Controller 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.
Function
ASIC Test Mode Enable. For normal USB Host Controller operation this register must be set
to 0.
Function
ASIC Operational Mode Enable. For normal USB Host Controller operation this register must
remain as 0.
