reading these 8 bits returns 01H
this register specifies, in units of PCI-bus clocks, the
value of the latency timer for this PCI-bus master
this value must be added to the register offset to claim
access to the programming registers; the lower 8 bits
are forced to zero
this value will be loaded after a PCI reset from external
hardware using the I

The interrupt pin register tells which interrupt pin the
device uses. This device uses interrupt pin INTA#.
When these bits are read they return 01H.
the interrupt line register tells which input of the system
interrupt controller the device’s interrupt pin is
connected to
