For instruction addressing, up to 16 MB of linear address space (program space) and an internal RAM
area are supported. Up to 4 GB of linear address space (data space) is supported for operand address-
ing (data access). In the 4 GB address space, it seems that there are sixty-four 64 MB physical address
spaces. This means that the same 64 MB physical address space is accessed, regardless of the values
of bits 31 to 26.
