Operating Modes and On-Chip Memory
Technical Data
86
Since the direct addressing mode accesses RAM more quickly and
efficiently than other addressing modes, many applications will find the
default locations of registers and on-board RAM at the bottom of
memory to be the most advantageous.
When RAM and the registers are both mapped to different 4-K
boundaries, the registers are mapped at $x000–$x07F, and RAM is
moved to $x000–$x2FF ($x000–x3FF for the [7]11KS2).
