9. Memory Organization

The memory organization of the CIP-51 System Controller is similar to that of a standard 8051. There are

two separate memory spaces: program memory and data memory. Program and data memory share the

same address space but are accessed via different instruction types. The memory organization of the

C8051F91x-C8051F90x device family is shown in Figure 9.1
