Figure 10. Automatic Disconnect Sequencing Mode
In manual disconnect mode, software has to perform each part of the disconnection sequence. Figure 11 is an
example of the manual disconnection sequence. There could be several other ways to implement this protocol.
During the manual disconnection, PCIBus may or may not idle; it will depend on the software implementation
of the system.
