9.4.
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. There are 256 bytes of internal data
memory and 32k bytes (C8051F360/1/2/3/4/5/6/7) or 16k bytes (C8051F368/9) of internal program mem-
ory address space implemented within the CIP-51. The CIP-51 memory organization is shown in
Figure 9.2.
9.4.1. Program Memory
The CIP-51 core has a 64 kB program memory space. The C8051F360/1/2/3/4/5/6/7 implement 32 kB of
this program memory space as in-system, re-programmable Flash memory, organized in a contiguous
block from addresses 0x0000 to 0x7BFF. Addresses above 0x7BFF are reserved on the 32 kB devices.
The C8051F368/9 implement 16 kB of Flash from addresses 0x0000 to 0x3FFF.
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 Section “13. Flash Memory” on page 135 for further details.
