cycles for each instruction.
8.1.2. MOVX Instruction and Program Memory
The MOVX instruction is typically used to access external data memory (Note: the C8051F300/1/2/3/4/5
does not support external data or program memory). In the CIP-51, the MOVX instruction accesses the on-
chip program memory space implemented as re-programmable Flash memory. This feature provides a
mechanism for the CIP-51 to update program code and use the program memory space for non-volatile
data storage. Refer to
