3.3.3 Internal Data Memory Mapping
Internal data memory locates in SRAM0 at the address from 0x9F00 to 0x9FFF as showed in XFigure 3-2 Internal
data memory is mapped in XFigure 3-3. The memory space is shown divided into three blocks, which are generally
referred to as the Lower 128, the Upper 128, and SFR space.
