Signal Descriptions

This chapter presents the LSI53C896 pin configuration and signal
definitions using tables and illustrations.

Figure 3.1

is the functional

signal grouping. The signal descriptions begin with

Table 3.2

. The signal

descriptions are organized into functional groups:

Section 3.1, “Internal Pull-ups on LSI53C896 Signals”

Section 3.2, “PCI Bus Interface Signals”

Section 3.3, “SCSI Bus Interface Signals”

Section 3.4, “Flash ROM and Memory Interface Signals”

Section 3.5, “Test Interface Signals”

Section 3.6, “Power and Ground Signals”

Section 3.7, “MAD Bus Programming”

The PCI Interface signals are divided into the following functional groups:

System Signals

,

Address and Data Signals

,

Interface Control Signals

,

Arbitration Signals

,

Error Reporting Signals

,

Interrupt Signals

,

SCSI Function A GPIO Signals

, and

SCSI Function B GPIO Signals

.

The SCSI Bus Interface signals are divided into

SCSI Function A Signals

,

and

SCSI Function B Signals

groups.

A slash (/) at the end of a signal name indicates that the active state
occurs when the signal is at a LOW voltage. When the slash is absent,
the signal is active at a HIGH voltage.
