Table 6. Signal Functional Description (Sheet 1 of 6)
Secondary multiplexed signals are shown in brackets.
Notes:
1. Receiver input has hysteresis.
2. Must pull up. See “Pull-Up and Pull-Down Resistors” on page 29 for recommended termination values.
3. Must pull down. See “Pull-Up and Pull-Down Resistors” on page 29 for recommended termination values.
4. If not used, must pull up.
5. If not used, must pull down.
6. Strapping input during reset; pull up or pull down as required.
7. Pull-up may be required. See “External Bus Control Signals” on page 30.

PCI Address/Data Bus. Multiplexed address and data bus.
Note: The target device number is driven on PCIAD11:31 for PCI
Type 0 configuration transactions.
Connect the target IDSEL associated with device:
1 to PCIAD16
2 to PCIAD17
...
21 to PCIAD31.
PCI bus command and byte enables.
PCIClk is used as the asynchronous PCI clock when in asynch mode.
PCIFrame is driven by the current PCI bus master to indicate the
beginning and duration of a PCI access.
PCI parity. Parity is even across PCIAD00:31 and PCIC3:0/BE3:0.
PCIParity is valid one cycle after either an address or data phase.
The PCI device that drove PCIAD00:31 is responsible for driving
PCIParity on the next PCI bus clock.
PCIIRDY is driven by the current PCI bus master. Assertion of
PCIIRDY indicates that the PCI initiator is ready to transfer data.
The target of the current PCI transaction drives PCITRDY. Assertion
of PCITRDY indicates that the PCI target is ready to transfer data.
The target of the current PCI transaction can assert PCIStop to
indicate to the requesting PCI master that it wants to end the current
transaction.
PCIDevSel is driven by the target of the current PCI transaction. A
PCI target asserts PCIDevSel when it has decoded an address and
command encoding and claims the transaction.
PCIIDSel is used during configuration cycles to select the PCI slave
interface for configuration.
PCI interrupt. Open-drain output (two states; 0 or open circuit)
or
Peripheral write enable. Low when any of the four PerWBE0:3 write
byte enables are low.
PCISErr is used for reporting address parity errors or catastrophic
failures detected by a PCI target.
PCIPErr is used for reporting data parity errors on PCI transactions.
PCIPErr is driven active by the device receiving PCIAD00:31,
PCIC3:0/BE3:0, and PCIParity, two PCI clocks following the data in
which bad parity is detected.
PCI specific reset.
Multipurpose signal, used as PCIReq0 when internal arbiter is used,
and as Gnt when external arbiter is used.
