Next Pointer (NEXT) — RO. This field indicates the location of the next pointer in the
list.
Capability ID (CID) — RO. Capabilities ID indicates MSI.
Reserved
64 Bit Address Capable (C64) — RO. Capable of generating a 32-bit message only.
Multiple Message Enable (MME) — R/W. These bits are R/W for software
compatibility, but only one message is ever sent by the root port.
Multiple Message Capable (MMC) — RO. Only one message is required.
MSI Enable (MSIE) — R/W.
0 = Disabled.
1 = Enabled and traditional interrupt pins are not used to generate interrupts.
NOTE: CMD.BME (D28:F0/F1/F2/F3/F4/F5:04h:bit 2) must be set for an MSI to be
Address (ADDR) — R/W. This field contains the lower 32 bits of the system specified
message address; always DWord aligned.

generated. If CMD.BME is cleared, and this bit is set, no interrupts (not even pin
based) are generated.
