BASEL (Base Address Lower): These bits define the memory space base address of the
(CRG).
PRE (Prefetch): This is a read-only register that reflects the ability of the function to support
prefetching. The CRG does not support prefetching.
MTYPx (Memory Type): These bits are hard-wired to 10b to indicate that the CRG can be
located anywhere in the 64-bit address space.
IO/MEM (I/O Space Indicator): This bit is set to a zero indicating this resource is a memory
space resource. The CRG can only be mapped to memory space.
