Memory Organization
The memory space of the C166S has a “Von Neumann” architecture. This means that
code and data are accessed within the same linear address space. All of the physically
separated memory areas, including internal ROM/FLASH/DRAM (where integrated),
DPRAM, the internal Special Function Register (SFR) and Extended Special Function
Register (ESFR) areas, and external memory are mapped into one common address
space.
