Figure 10. System Diagram: Single-Slot Hot-Plug for TPS2342
Single-slot hot-plug support is enabled for each bridge through strapping options on [B,A]_GNT_L4, as
reflected in Dev[B,A]:0x40[SSS_L].
The AMD-8132 tunnel drives all slot signals low throughout the duration of a cold reset and continues to do so
until after the TPS* hot-plug power controller applies power to the adapter. The AMD-8132 tunnel interprets
the SHPC commands to control the signals in the power only, slot enable, and slot disable sequences and to
receive BUSEN_L and CLKEN_L output from the TPS* to control its bus signal state. Figure 11 shows how
signals are controlled by the AMD-8132 tunnel during the sequence initiated by the slot enable command and
the slot disable command.
