Description
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.
SCSI Data includes the following data lines and parity
signals: SD[15:0]/ (16-bit SCSI data bus), and SDP[1:0]/
(SCSI data parity bits).
