Description
Driver direction control for SCSI parity signals. In the
LSI53C875J and LSI53C875JB, this pin is replaced by
the TCK JTAG signal. If the device is used in a wide
differential system, use the SDIRP0 pin to control the
direction of the differential transceiver for both the SP0
and SP1 signals. The SDIRP0 signal is capable of
driving both direction inputs from a transceiver.
Driver Enable Control for SCSI SEL/ signal.
Driver Enable Control for SCSI RST/ signal.
Driver Enable Control for SCSI BSY/ signal.
Direction Control for initiator driver group.
Direction Control for target driver group.
