9.2.1. Program Memory
The CIP-51 core has a 64 kB program memory space. The C8051F330/1 implements 8 kB of this program
memory space as in-system, re-programmable Flash memory, organized in a contiguous block from
addresses 0x0000 to 0x1DFF. Addresses above 0x1DFF are reserved on the 8 kB devices. The
C8051F332/3 and C8051F334/5 implement, in contiguous blocks, 2 and 4 kB, from addresses 0x0000 to
0x07FF or 0x0000 to 0x0FFF, respectively. Addresses above 0x0800 and 0x1000 are reserved on the 2
and 4 kB devices, respectively.
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 write instruction. This fea-
ture provides a mechanism for the CIP-51 to update program code and use the program memory space for
non-volatile data storage. Refer to
