3.11 Reset
The PCI Express specification defines three distinct types of reset: cold, warm, and hot.
The fundamental reset that occurs following initial power on is considered a hot reset.
The assertion of the PRST# or WARM_RST# pins are considered warm resets. The
receipt of the inband reset training sequence is considered a hot reset.
Sticky bits are preserved under the WARM_RST# and inband hot reset conditions.
Additional reset details are specified in
Chapter 17.0, “Clocking and Reset” .
