2 Signal Description  
The “#” symbol at the end of a signal name indicates that the active, or asserted state occurs when  
the signal is at a low voltage level. When “#” is not present after the signal name the signal is  
asserted when at the high voltage level.  
Note: Segment “A” signifies the interface of the PCI bus segment of the Intel® 6702PXH 64-bit PCI  
Hub. All Intel® 6702PXH 64-bit PCI Hub PCI bus signals will use the letter “A” in these signal  
names. For example, in the PCI Bus interface, PAAD[31:0] refer to the AD bus signals on  
PCI Bus A.  
The following notations are used to describe the signal type:  
P
Power pin  
I
Input pin  
O
I/O  
Output pin  
Bi-directional Input/Output pin

PCI Express Compensation Inputs: Analog signals.  
EXP_RXP[7:0]  
EXP_RXN[7:0]  
PCI Express Serial Data Inputs: PCI Express differential data receive signals.  
For 4X mode, only signals EXP_RXP[3:0] and EXP_RXN[3:0] are used.  
For 8X mode, all of these signals, EXP_RXP[7:0] and EXP_RXN[7:0], are  
used.  
These signals are the PExRp[7:0] and PExRn[7:0] signals per the PCI SIG  
convention.  
EXP_TXP[7:0]  
EXP_TXN[7:0]  
O
PCI Express Serial Data Outputs: PCI Express differential data transmit  
signals.  
For 4X mode, only signals EXP_TXP[3:0] and EXP_TXN[3:0] are used.  
For 8X mode, all of these signals, EXP_TXP[7:0] and EXP_TXN[7:0], are used.  
These signals are the PExTp[7:0] and PExTn[7:0] signals per the PCI SIG  
convention.
