Note: Where information in this section applies to both the TPS2340A and TPS2342 hot-plug
Isolation switches are not required if the bridge is connected to a single hot-plug slot. The AMD-8132 tunnel
provides the isolation function by appropriately controlling the slot signals. The TPS* hot-plug power
controller and power switches are still required.
