8.2.
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 CIP-51 memory organization is
shown in Figure 8.2.
8.2.1. Program Memory
The CIP-51 core has a 64k-byte program memory space. The C8051F310/1 and C8051F312/3/4/5 imple-
ment 16 and 8 kB, respectively, of this program memory space as in-system, re-programmable Flash
memory, organized in a contiguous block from addresses 0x0000 to 0x3FFF or 0x0000 to 0x1FFF.
Addresses above 0x3E00 are reserved on the 16 kB devices.
Program memory is normally assumed to be read-only. However, the CIP-51 can write to program memory
by setting the Program Store Write Enable bit (PSCTL.0) and using the MOVX instruction. This feature pro-
vides a mechanism for the CIP-51 to update program code and use the program memory space for non-
volatile data storage. Refer to
