The local access window registers exist as part of the local access block in the general utilities

registers. See Section 2.3.3, “General Utilities Registers.” A detailed description of the local

access window registers is given in the following sections. Note that the minimum size of a

window is 4 Kbytes, so the low order 12 bits of the base address cannot be specified.
