3.3.2 SCSI Function B Signals

This section describes the signals for the SCSI Function B Signals group.
It is divided into two tables:

SCSI Function B Signals

and

SCSI Function B_SCRTL Signals

.

Table 3.13

describes the SCSI Function B Signals group.

SCSI

SCSI Function B Data and Parity.

LVD Mode: Negative half of LVDlink
pair for SCSI data and parity lines.
B_SD[15:0]

are the 16-bit SCSI data

bus, and B_SDP[1:0]

are the SCSI

data parity lines.

SE Mode: B_SD[15:0]

are the 16-bit

SCSI data bus, and B_SDP[1:0]

are

the SCSI data parity lines.

HVD Mode: B_SD[15:0]

and

B_SDP[1:0]

are the SCSI data bus.

SCSI

SCSI Function B Data and Parity.

LVD Mode: Positive half of LVDlink pair
for SCSI data lines. B_SD[15:0]+ are
the 16-bit data bus, and B_SDP[1:0]+
are the SCSI data parity lines.

SE Mode: B_SD[15:0]+ and
B_SDP[1:0]+ are at 0 V.

HVD mode: B_SD[15:0]+ and
B_SDP[1:0]+ are driver directional
control for SCSI data lines.
