Preliminary Data Sheet
Signal Name
Address/Data bus (bidirectional).
Provides timing to the PCI interface for PCI transactions.
Even parity.
PCI Command/Byte Enables
Indicates the driving device has decoded its address as the
target of the current access.
Driven by the current master to indicate beginning and
duration of an access.
Indicates that the specified agent is granted access to the bus.
When the internal arbiter is enabled, output is PCIGnt0. When
the internal arbiter is disabled, output is Req.
Indicates that the specified agent is granted access to the bus.
Used as a chip select during configuration read and write
transactions.
Level sensitive PCI interrupt.
Indicates initiating agent’s ability to complete the current data
phase of the transaction.
Reports data parity errors during all PCI transactions except a
Special Cycle.
Indicates to the PCI arbiter that the specified agent wishes to
use the bus. When the internal arbiter is enabled, input is
PCIReq0. When internal arbiter is disabled, input is Gnt.
An indication to the PCI arbiter that the specified agent wishes
to use the bus.
Brings PCI device registers and logic to a consistent state.
Reports address parity errors, data parity errors on the Special
Cycle command, or other catastrophic system errors.
Indicates the current target is requesting the master to stop the
current transaction.
I
phase of the transaction.
ndicates the target agent’s ability to complete the current data
