The base address field is the upper 20 bits of the MBAR that provides for block starting
locations in increments of 4-Kbytes.
The address space field allows particular address spaces to be masked, placing the 4K
module block into a particular address space(s). If an address space is masked, an
access to the register block location in that address space becomes an external access.
The module block is not accessed. The address space bits are as follows:
For each address space bit:
This bit indicates when the contents of the MBAR are valid. The base address value is
not used; therefore, all internal module registers are not accessible until the V-bit is set.
