Register 3 - OUMWTVR3
The Outbound Upper 32-bit Memory Window Translate Value Register 3 (OUMWTVR3)
defines the upper 32-bits of address used during a dual address cycle. This enables the
outbound ATU to directly address anywhere within the 64-bit host address space. When
this register is all-zero, then a SAC is generated on the PCI bus.
