P_GNT[3:1]#

Sync (P)

ActLow

PCI Bus Grant:

• External arbiter mode: Not used

• Internal arbiter mode: These are three of four output grant

signals from the internal arbiter.

P_REQ[3:1]#

Sync (P)

Rst (P)

ActLow

PCI Bus Request:

• External arbiter mode: Not used

• Internal arbiter mode: These are three of four input request

signals to the internal arbiter.

P_PCIXCAP

PCI-X Capability: Refer to the Intel® 81341 and Intel® 81342 I/O

Processors Specification Update for more details.

P_BMI

Sync (P)

Rst (P)

PCI Bus Master Indicator indicates that the I/O processor is

mastering a transaction on the PCI bus.

P_CAL[0]

PCI Calibration is connected to an external calibration resistor. The

CCVIO

PCI output drivers reference the resistor to dynamically

adjust the drive strength to compensate for voltage and

temperature variations. This pin is connected through a 22.1 ohm

1% resistor to ground.

P_CAL[1]

PCI Calibration is connected to an external calibration resistor. The

PCI output drivers reference the resistor to dynamically adjust the

ODT resistance to compensate for voltage and temperature

variations. This pin is connected through a 121 ohm 1% resistor to

ground.

P_CAL[2]

PCI Calibration is connected to an external calibration resistor. The

CC3P3

PCI output drivers reference the resistor to dynamically

adjust the drive strength to compensate for voltage and

temperature variations. This pin is connected through a 22.1 ohm

1% resistor to ground.

P_CLKIN

PCI Bus Input Clock provides the AC timing reference for all PCI

transactions.

P_CLKOUT

PCI Bus Output Clock: When

REFCLKN/REFCLKP are used, the I/O

processor can generate the PCI output clocks. This pin is then

connected to

P_CLKIN and trace length matched to

P_CLKO[3:0].

P_CLKO[3:0]

PCI Bus Output Clocks: When

REFCLKN/REFCLKP are used, the I/

O processor can generate the PCI output clocks. These pins then

provide the PCI clocks to devices on the PCI bus.
