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.
