The following options are available to reset the PCIe card.
Resetting the add-on card
It is recommended to implement the reset for the attached PCIe device (add-on card) using an AND gate logic. One of the AND gate input is the processor general purpose input/output (GPIO) pin and has provision for pulldown. The other input of the AND gate is the processor Main Domain warm reset status output (RESETSTATz) signal.
Resetting the processor
It is recommended to connect the reset output from the add-on card (PCIe connector) as one of the inputs to the ANDing logic used to generate the processor MCU Domain cold reset (MCU_PORz).
