8 mA PCI Interrupt Request. This signal, when asserted LOW,
indicates that an interrupting condition has occurred and
that service is required from the host CPU. The output
drive of this pin is open drain.

SCSI Clock is used to derive all SCSI-related timings. The
speed of this clock is determined by the application's
requirements. In some applications, SCLK may be sourced
internally from the PCI bus clock (CLK). If SCLK is
internally sourced, then the SCLK pin should be tied low.
