The AMD-8132 tunnel is designed so only active-low interrupts from [B,A]_PIRQ[D:A]_L are supported
when in single-slot support mode while the slot is not enabled. If the IOAPIC is programmed for active high
interrupts in this mode, then spurious interrupt requests are generated.

1.3.7.3.1 TPS2340A Serial Interface
The hot-plug serial interface operates at 8.33 MHz. It converts SHPC commands to a serial format to
communicate with the TPS2340A hot-plug power controllers. It is also used to read status information from the
TPS2340A hot-plug power controllers and update the AMD-8132 tunnel SHPC status registers accordingly.
There are two different groups of serial interface signals.
For additional information, see the TPS2340A product information.

• Common serial signals are connections between the AMD-8132 tunnel and all TPS2340A hot-plug power
• Bridge specific signals are connections between the AMD-8132 tunnel and only those TPS2340A hot-plug
controllers and are shared across both PCI/PCI-X bridges. These signals are: HPSIC, HPSIL_L, HPSOC,
HPSOD, HPSOR_L.
power controllers connected to a particular bridge. These signals are: [B,A]_HPSID, [B,A]_HPSOLC_L,
[B,A]_HPSORLC_L, [B,A]_HPSORR_L.
