Description
48 mA, SCSI data/parity output bus. These pins are
active LOW SCSI data signals. These signals are
actively deasserted when Active Negation is enabled
and the chip is active on the SCSI bus; otherwise,
these are open drain SCSI outputs.
48 mA, open drain SCSI I/Os, active LOW. The Reset
SCSI Bus command that causes the FSC to drive
RST/ true for 25–40 s, depending on the CLK
frequency and clock conversion factor.
48 mA, SCSI I/O. Asserted only in target mode. This
signal is actively deasserted when Active Negation is
enabled and the chip is active as a target on the SCSI
bus; otherwise, this is an open drain SCSI output.
48 mA, SCSI I/O. Driven by the FSC in initiator mode
only. This signal is actively deasserted when
Active Negation is enabled and the chip is active as
an initiator on the SCSI bus; otherwise, this is an
open drain SCSI output.
48 mA, open drain output, Schmitt trigger input. In
initiator mode it is an output, and is automatically
asserted when the FSC detects an incoming parity
error, or may be asserted by certain FSC commands.
In target mode, this signal is an input.
SCSI phase signals. They are 48 mA outputs in target
mode, and Schmitt trigger inputs in initiator mode.
