PCIX0:2Par/PCIX0:2ECC0

Even parity indicator or ECC0.

Normally used to indicate even parity across

PCIAD31:00 and BE3:0.

Used as ECC0 for PCIX0:2 mode 2.

I/O

3.3V PCI or

1.5V PCI for mode 2

PCIX0:1Par64/PCIX0:1ECC7

Even parity indicator or ECC7.

Normally used to indicate even parity across

PCIAD63:32 and BE7:4 for PCI0 and PCI1.

Used as ECC7 for PCIX0:1 mode 2.

I/O

3.3V PCI or

1.5V PCI for mode 2

PCIX0:2PErr

Reports data parity errors during all PCI transactions

except a Special Cycle.

I/O

3.3V PCI

PCIX0:2Req0:1

PCIX0:1Req2:3

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.

I/O

3.3V PCI

PCIX0:1Req64/PCIX0:1ECC6

Request 64-bit transfer or ECC6.

Normally used by the current bus master to indicate a

64-bit transfer.

Used as ECC6 for PCIX2 mode 2.

I/O

3.3V PCI or

1.5V PCI for mode 2

PCIX0:2Reset

Sets PCI device registers and logic to a consistent state.

3.3V PCI

PCIX0:2SErr

Reports address parity errors, data parity errors on the

Special Cycle command, or other catastrophic system

errors.

I/O

3.3V PCI

PCIX0:2Stop

Indicates the current target is requesting the master to

stop the current transaction.

I/O

3.3V PCI

PCIX0:2TRDY

Indicates the target agent’s ability to complete the

current data phase of the transaction.

I/O

3.3V PCI

PCIX0:2VC

Voltage control output. Used to control the voltage

regulator supplying the PCI I/O voltage. See PCI-XCap

signal.

0 = 3.3V (PCI I/O)

1 =1.5V (PCI-X DDR)

3.3(1.5)V PCI

PCIX0:2VRef0:1

Voltage reference input for PCI-X mode 2/DDR (1.5V)

I/O. Not used for PCI or PCI-X mode 1.

IVPCIXDDR
