C8051F340/1/2/3/4/5/6/7/8/9
9.2.1. Program Memory
The CIP-51 core has a 64k-byte program memory space. The C8051F340/1/2/3/4/5/6/7/8/9 implements
64k or 32k bytes of this program memory space as in-system, re-programmable Flash memory. Note that
on the C8051F340/2/4/6 (64k version), 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
