Memory Space Base Address
These 8 bits select the base address for this 16MB memory space used by the 69000 for the
memory mapped registers and linear accesses to the frame buffer.
Memory Space Size
These 20 bits always return 0 to indicate that the size of this memory space is 16MB.
Prefetchable
This bit always returns a value of 0 when read, indicating that the data in this 16MB memory space
should not be prefetched by the CPU.
Memory Type
These 2 bits always return values of 0 when read, indicating that this 16MB memory space may be
placed anywhere in the system’s 32-bit address space by the system’s PCI configuration software.
Memory/IO Space Indicator
This bit always returns a value of 0 when read, indicating that this is a memory space, not an I/O
