MSI Message Upper Address
The LSISAS1064 supports 64-bit MSI message. This
register contains the upper 32 bits of the 64-bit message
address, which the system specifies. The host system
software can program this register to 0x0000 to force the
PCI function to generate 32-bit message addresses.

The LSISAS1064 sends an interrupt message by writing
a Dword to the address held in the
Address
register forms bits [15:0] of the Dword message that the
PCI function passes to the host. The PCI function drives
bits [31:16] of this message to 0x0000.
