PCI Bus Interface Signals 3-5
3.2 PCI Bus Interface Signals
The PCI Bus Interface Signals section contains tables describing the
signals for the following signal 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 .
3.2.1 System Signals
Table 3.2 describes the signals for the System Signals group.
Table 3.2 System Signals
Name Bump Type Strength Description
CLK H3 I N/A Clock provides timing for all transactions on the PCI bus and
is an input to every PCI device. All other PCI signals are
sampled on the rising edge of CLK, and other timing
parameters are defined with respect to this edge. Clock can
optionally serve as the SCSI core clock, but this may effect fast
SCSI-2 (or faster) transfer rates.
RST/ G1 I N/A Reset forces the PCI sequencer of each device to a known
state. All T/S and S/T/S signals are forced to a high impedance
state, and all internal logic is reset. The RST/ input is
synchronized internally to the rising edge of CLK. The CLK
input must be active while RST/ is active to properly reset the
device.
