CIP-51 Instruction Set Summary, which includes the mnemonic, number of bytes, and number of clock
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
