5.7.1.3. PCI Express Mailbox Registers

The PCI Express Root Complex typically requires write access to a set of PCI Express to Avalon-MM Mailbox registers and read-only access to a set of Avalon-MM to PCI Express mailbox registers. Eight mailbox registers are available.

The PCI Express to Avalon MM Mailbox registers are writable at the addresses shown in the following table. Writing to one of these registers causes the corresponding bit in the Avalon-MM Interrupt Status register to be set to a one.

The Avalon-MM to PCI Express Mailbox registers are read at the addresses shown in the following table. The PCI Express Root Complex should use these addresses to read the mailbox information after being signaled by the corresponding bits in the Avalon-MM to PCI Express Interrupt Status register.
