Functional Description
2.7 Signal Descriptions
Figure 2-2 illustrates the SYM53C141 signal groupings. A description of
the signals follows. For specific signal timings, see AC Characteristics in
Chapter 4.
Figure 2.2
SYM53C141 Signal Grouping
2.7.1 Data and Parity
The signals named A_SD[15:0]/ and A_SDP[1:0]/ are the data and parity
signals from the A-side; the signals named B_SD[15:0] and B_SDP[1:0]
±
are the data and parity signals from the B-side of the SYM53C141.
These signals are sent and received from the SYM53C141 through a
SCSI compatible driver and receiver logic designed into the SYM53C141
interfaces. This logic provides the necessary drive, sense thresholds, and
input hysteresis to function correctly in a SCSI bus environment as
defined in ANSI Standard for SCSI-1, SCSI-2, and SCSI-3.
