Signal Description  
2.9  
Pin Straps  
The following signals are used for static configuration. These signals are all sampled on the rising  
edge of PWROK, and then return to normal usage afterward.  
Table 2-11. Normal Functional Pin Straps (Sheet 1 of 2)  
Strap Pin  
Function  
HPA_SIC  
Intel Test Mode:  
1 = Normal operation  
0 = Reserved  
HPA_SID  
Intel Test Mode:  
1 = Reserved  
0 = Normal operation  
HPA_SLOT[3]  
HPA_SLOT[2:0]  
Enable/Disable PCI Hot Plug Mode:  
1 = Hot Plug Mode Enabled  
0 = Hot Plug Mode Disabled  
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)  
PA133EN  
Only relevant when Hot Plug Mode is disabled (HPA_SLOT[3] = 0) OR when in one-slot-  
no-glue hot plug mode (HPA_SLOT[3:0] = 1111), AND when in PCI-X Mode  
(PAPCIXCAP = 1).  
133 MHz PCI-X Enable/Disable: Determines the maximum frequency (100 MHz or  
133 MHz) of the PCI bus segment when in PCI-X Mode:  
1 = 133 MHz PCI-X capable  
0 = 100 MHz PCI-X max bus frequency
