Signal Name
Address/Data bus (bidirectional).
PCI-X Command[Byte Enables]
Capable of PCI-X operation.
PCI-X devices are 133 MHz capable.
Provides timing to the PCI interface for PCI transactions.
Note:
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 using an external PCI/PCI-X arbiter, connect the external
arbiter's Grant line to this signal.
Indicates that the specified agent is granted access to the bus.
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.
Capable of 66MHz operation.
Even parity across PCIAD32:63 and PCIXC0:3[BE4:7].
Even parity across PCIAD0:31 and PCIXC0:3[BE0:3].
Reports data parity errors during all PCI transactions except a
Special Cycle.
An indication to the PCI-X arbiter that the specified agent wishes
to use the bus. When using an external PCI/PCI-X arbiter, connect
the external arbiter's Request line to this signal.
An indication to the PCI-X arbiter that the specified agent wishes
to use the bus.
Asserted by the current bus master, indicating a 64-bit transfer.
Indicates the target can transfer data using 64 bits.
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.
If the PCI-X interface is not being used, drive this pin with a
3.3V clock signal at a frequency between 1 and 66MHz
