3.4WINDOWING

Windowing maps a segment of higher memory (the upper register file or peripheral SFRs) into the lower register file. The window selection register (WSR) selects a 32-, 64- or 128-byte seg- ment of higher memory to be windowed into the top of the lower register file space. Table 3-4 lists the WSR values for windowing the upper register file for both the 8XC196Lx and 8XC196Kx.

NOTE: Locations 1FE0–1FFFH contain memory-mapped SFRs that cannot be accessed through a window. Reading these locations through a window returns FFH; writing these locations through a window has no effect.
