HOT PLUG OPERATION
The PI7C9X20508GP is compliant with the PCI Standard Hot-Plug Controller (SHPC) and Subsystem
Specification Revision 1.0.
Systems with the Hot Plug capability allow the attachment and removal of components from the running system
without severely affecting the normal operation of the system. This feature prevents down-time of the system when
faulty components need to be replaced or the re-configuration of the system needs to be performed. This feature also
allows the system to isolate a faulty component and maintain the stability of the rest of the system upon the
detection of such event. Each downstream port of the device has its own Hot Plug Controller, which operates
independently from the others. The Hot Plug Controller of the device provides the parallel interface bus to the slot,
and, therefore, no extra logic is required to convert the signals from the serial interface bus into parallel.
The Hot Plug operation of the PI7C9X20508GP is implemented by the Hot Plug Signal Pins (Section 3.3) and Hot
Plug Capability related register sets (Section 7.2.71 to 7.2.73). The Hot Plug Signal Pins of the device consist of
"PWR_IND", "ATT_IND", "ATT_BTN", "MRL_PDC", "PWR_ENA_L" and "PWR_FLT" pins. The Hot Plug
Capability register sets provide Hot Plug related status reporting. Additionally, the register sets provide interrupt
messaging, which signal the occurrences of various Hot Plug events that take place on the slots. Upon receiving of
the interrupt events, the system software can use the Hot Plug Capability registers to respond to these events.
