Table 8. Signal Functional Description (Sheet 1 of 9)
Notes:
1. Receiver input has hysteresis
2. Must pull up (recommended value is 3 kΩ to OV
3. Must pull down (recommended value is 1 kΩ)
4. If not used, must pull up (recommended value is 3 kΩ to OV
5. If not used, must pull down (recommended value is 1 kΩ)
6. Strapping input during reset; pull-up or pull-down required

Signal Name
Address/Data bus (bidirectional).
PCI Command/Byte Enables
Provides timing to the PCI interface for PCI transactions.
Indicates the driving device has decoded its address as the
target of the current access.
(PCI 2.2 specification requires 8.2K
Driven by the current master to indicate beginning and duration
of an access.
(PCI 2.2 specification requires 8.2K
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.
(PCI 2.2 specification requires 8.2K
Indicates that the specified agent is granted access to the bus.
Used only when internal PCI arbiter enabled.
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.
(PCI 2.2 specification requires 8.2K
Even parity.
Reports data parity errors during all PCI transactions except a
Special Cycle.
(PCI 2.2 specification requires 8.2K
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. Used only when internal PCI arbiter enabled.
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.
(PCI 2.2 specification requires 8.2K
Indicates the current target is requesting the master to stop the
current transaction.
