Table 2-5. General Hot Plug Interface A Signals – All Hot Plug Modes  
Signal  
Type  
Description  
HPA_SLOT[3]  
I
Enable/Disable PCI Hot Plug Mode:  
1 = Hot Plug Mode Enabled  
0 = Hot Plug Mode Disabled  
HPA_SLOT[2:0]  
I
Hot Plug Mode / # of PCI Slots: Used in conjunction with HPA_SLOT[3]  
signal to determine PCI Hot Plug Mode and number of PCI slots on a bus  
segment.  
HPA_SLOT[3:0] = Hot Plug Mode Enable/Disable, # of PCI slots  
0000 = hot plug disabled, 1 slot (optional)  
0001 = hot plug disabled, 2 slots (optional)  
0010 = hot plug disabled, 3 slots (optional)  
0011 = hot plug disabled, 4 slots (optional)  
0100 = hot plug disabled, 5 slots (optional)  
0101 = hot plug disabled, 6 slots (optional)  
0110 = hot plug disabled, 7 slots (optional)  
0111 = hot plug disabled, 8 slots (optional)  
1000 = reserved  
1001 = hot plug enabled, 1 slot (parallel mode)  
1010 = hot plug enabled, 2 slots (parallel mode)  
1011 = hot plug enabled, 3 slots (serial mode)  
1100 = hot plug enabled, 4 slots (serial mode)  
1101 = hot plug enabled, 5 slots (serial mode)  
1110 = hot plug enabled, 6 slots (serial mode)  
1111 = hot plug enabled, 1-slot-no-glue (parallel mode)

Signal  
Type  
Description  
HPA_SLOT[3:0]  
I
Hot Plug Mode Enable / # of PCI Slots: Used to enable/disable hot plug  
mode and to determine number of hot plug slots.  
HPA_SLOT[3:0]:  
1011 = hot plug enabled, 3 slots (serial mode)  
1100 = hot plug enabled, 4 slots (serial mode)  
1101 = hot plug enabled, 5 slots (serial mode)  
1110 = hot plug enabled, 6 slots (serial mode)  
HPA_PRST#  
O
Primary Bus Reset Out (HPA_PRST#): This is asserted whenever the  
primary side of the Intel® 6702PXH 64-bit PCI Hub goes through a reset,  
even if hot plug is disabled. Resets the slot interface logic in hot plug serial  
mode.  
HPA_SIC  
HPA_SID  
O
I
Serial Input Clock: This signal is normally high. It pulses low to shift  
external serial input shift register data one bit position. (The shift registers  
should be similar to standard “74x165” series).  
Serial Input Data: Data shifted in from external logic on HPA_SIC.
