The register block can be mapped to any 2K byte boundary within the
standard 64K byte address space by manipulating bits REG[15:11] in
the INITRG register. INITRG establishes the upper five bits of the
register block’s 16-bit address. The register block occupies the first 1K
byte of the 2K byte block. Default addressing (after reset) is indicated in
the table below. For additional information refer to
