9.2.1. Program Memory
The CIP-51 core has a 64k-byte program memory space. The C8051F34x implements 64k or 32k bytes of
this program memory space as in-system, re-programmable Flash memory. Note that on the 64k versions
of the C8051F34x, addresses above 0xFBFF are reserved.
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
