The register block can be mapped to any 2-Kbyte boundary within the
standard 64-Kbyte address space. The register block occupies the first 512
bytes of the 2-Kbyte block. This register map shows default addressing
after reset.
In normal modes, writing to a reserved bit has no effect and reading returns
logic 0.
In any mode, writing to an unimplemented bit has no effect and reading
returns a logic 0.
