Signal Description  
2.12.4.1  
Serial Input Stream  
The input stream shifted out by the Intel® 6700PXH 64-bit PCI Hub consists of 48 bits and is  
fixed. If the board implements less than 6 slots in serial mode, a bit stream value of 1 must be  
shifted into the Intel® 6700PXH 64-bit PCI Hub for the slot locations not implemented. The  
sequence is shown below. Since the control bits corresponding to a slot are clustered into a group  
and the control bits for slot 1 come last, the Intel® 6700PXH 64-bit PCI Hub does not support  
stutter mode.

Serial Output Stream  
The sequence below shows how the slot outputs are scanned out in order. If the board implements  
less than six slots, then the serial input bits corresponding to those slots are arbitrary and are  
ignored by the Intel® 6700PXH 64-bit PCI Hub.
