Processor Configuration Registers
2.10.31 MC—Message Control Register
System software can modify bits in this register, but the device is prohibited from doing
so.
If the device writes the same message multiple times, only one of those messages is
ensured to be serviced. If all of them must be serviced, the device must not generate
the same message again until the driver services the earlier one.

Description
15:8 RO 00h Reserved
7RO 0b
64-bit Address Capable (64AC)
Hardwired to 0 to indicate that the function does not implement the upper 32
bits of the Message Address register and is incapable of generating a 64-bit
memory address.
This may need to change in future implementations when addressable
system memory exceeds the 32b/4 GB limit.
6:4 RW 000b
Multiple Message Enable (MME)
System software programs this field to indicate the actual number of
messages allocated to this device. This number will be equal to or less than
the number actually requested. The encoding is the same as for the MMC
field below.
3:1 RO 000b
Multiple Message Capable (MMC)
System software reads this field to determine the number of messages being
requested by this device.
000 = 1
All of the following are reserved in this implementation:
001 = 2
010 = 4
011 = 8
100 = 16
101 = 32
110 = Reserved
111 = Reserved
0RW 0b
MSI Enable (MSIEN)
This bit controls the ability of this device to generate MSIs.
0 = MSI will not be generated.
1 = MSI will be generated when we receive PME or HotPlug messages. INTA
will not be generated and INTA Status (PCISTS1[3]) will not be set.
