Output Control  
The output interface is responsible for driving six bits per slot. These signals are mapped onto  
Intel® 6700PXH 64-bit PCI Hub pins as shown in Table 2-24 and Table 2-25 for serial mode and  
Table 2-26 for parallel mode.  
POWER ENABLE: Connected to an analog component designed to regulate current and  
voltage of the PCI slot, and generates a (power) fault signal when an abnormal condition is  
detected.  
CLOCK ENABLE#: Connects the PCI clock signals of the PCI slot to the PCI bus via FET  
isolation switches.  
BUS ENABLE#: Connects the PCI bus signals of the PCI slot to the system bus PCI bus via  
FET isolation switches.  
RESET#: Connected to the RST# pin of the PCI slot.  
ATNLED#: Connected to the optional attention LED, which is yellow or amber in color.  
PWRLED#: Connected to the power LED, which is green in color.
