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.
