Bridge Reset Features
There are five bridge reset options that include internally-generated power-on reset, resets generated by
asserting input terminals, and software-initiated resets that are controlled by sending a PCI Express hot reset
or setting a configuration register bit. Table 3−1 identifies these reset sources and describes how the bridge
responds to each reset.
