Request FIFO
Read/Write
This register provides Request Free Message Frame Addresses (MFAs)
to the host system on reads and accepts Request Post MFAs from the
host system on writes. There is one Request FIFO register that is visible
to both PCI functions. The two PCI functions physically share this register.
Request FIFO
[31:0]
For reads, the Request Free MFA is empty and this
register contains 0xFFFFFFFF. For writes, the register
contains the Request Post MFA.
