We have a desire to use both the IRQ0 pin on the T2080 and receive the PCI assert/deassert INTB messages on PCIe4. The T2080 maps those two on top of each other. Is there a means of determining if the pin, or the PCIe bus is causing IRQ0 to be asserted. Can the state of the pin itself be read from a register, or is there a means to determine that the source was from PCIe instead of the pin. We are not using the IRQ0 pin for PCIe, rather another purpose.
