In reverse bridge mode, PI7C9X130 maps the interrupt message packets to PCI interrupt pins or MSI if
MSI is enable (see configuration register bit [16] of Offset F0h).
In forward bridge mode, PI7C9X130 maps the PCI interrupts pins or MSI if enable on PCI side to
interrupt message packets on PCIe side.
There are eight interrupt message packets. They are Assert_INTA, Assert_INTB, Assert_INTC,
Assert_INTD, Deassert_INTA, Deassert_INTB, Deassert_INTC, and Deassert_INTD. These eight
interrupt messages are mapped to the four PCI interrupts (INTA, INTB, INTC, and INTD). See table
10-1 for interrupt mapping information in reverse bridge mode. PI7C9X130 tracks the PCI interrupt
(INTA, INTB, INTC, and INTD) pins and maps them to the eight interrupt messages. See table 10-2
for interrupt mapping information in forward bridge mode.
