Signal Description  
Table 2-6. Serial Mode Hot Plug Signals – Interface A – 3 to 6 Slots (Sheet 2 of 2)  
Signal  
Type  
Description  
HPA_SIL#  
O
Serial Input Load: This signal is normally high. It pulses low to  
synchronously parallel load external serial input shift registers on the next  
rising edge of HPA_SIC.  
HPA_SOC  
O
Serial Output Clock: This signal is normally high. It pulses low to shift  
internal serial output shift register data one bit position. (The shift registers  
should be similar to standard “74x164” series.)  
HPA_SOD  
HPA_SOL  
O
O
Serial Output Data: Data is shifted out to external logic on HPA_SOC.  
Serial Output Non-Reset Latch Load: This signal is normally high. It  
pulses low to clock external latches (power-enable, clock-enable, slot bus-  
enable, and LED latches). The high edge acts as the clock.  
HPA_SOLR  
O
Serial Output Reset Latch Load: This signal is normally high. It pulses  
high to clock external latches (Reset latches) reading the serial output shift  
registers. The high edge acts as the clock.  
Table 2-7. Parallel Mode Hot Plug Signals – Interface A – 1 to 2 Slots (Sheet 1 of 4)  
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]:  
1111 = hot plug enabled, one-slot-no-glue hot plug mode  
1001 = hot plug enabled, 1 slot (parallel mode)  
1010 = hot plug enabled, 2 slots (parallel mode)  
HAATNLED_1#  
O
O
Slot 1 Attention LED: Control for attention LED of the first hot plug slot,  
which is yellow or amber in color. Only used when in one-slot-no-glue,  
single-slot parallel, or dual-slot parallel hot plug mode  
(HPA_SLOT[3:0] = 1111, 1001, or 1010).  
HPA_SOLR/  
HAATNLED2#  
Slot 2 Attention LED: Control for attention LED of the second hot plug slot,  
which is yellow or amber in color. Only used when in dual-slot parallel hot  
plug mode (HPA_SLOT[3:0] = 1010).  
PAGNT_[5]#/  
HABUSEN_1#  
O
O
I
Slot 1 Bus Enable: Bus enable signals that connect the PCI bus signals of  
the first PCI slot to the system bus PCI bus via FET isolation switches.  
Only used when in single-slot or dual-slot parallel hot plug mode  
(HPA_SLOT[3:0] = 1001 or 1010).  
PAGNT_[4]#/  
HABUSEN_2#  
Slot 2 Bus Enable: Bus enable signals that connect the PCI bus signals of  
the second PCI slot to the system bus PCI bus via FET isolation switches.  
Only used when in dual-slot parallel hot plug mode  
(HPA_SLOT[3:0] = 1010).  
PAIRQ_[8]#/  
HABUTTON_1#  
Slot 1 Attention Button: Optional. Attention button input signal connected  
to the first hot plug slot’s attention button. When low, indicates that the  
operator has requested attention. If attention button is not implemented,  
then this input must be wired to a high logic level.  
Only used when in one-slot-no-glue, single-slot or dual-slot parallel hot plug  
mode (HPA_SLOT[3:0] = 1111, 1001 or 1010).
