9.1.2. MOVX Instruction and Program Memory
In the CIP-51, the MOVX instruction serves three purposes: accessing on-chip XRAM, accessing off-chip
data XRAM (only on C8051F340/1/4/5/8 devices), and accessing on-chip program Flash memory. The
Flash access feature provides a mechanism for user software to update program code and use the pro-
gram memory space for non-volatile data storage (see
External Memory Interface (only on C8051F340/1/4/5/8 devices) provides a fast access interface to
off-chip data XRAM (or memory-mapped peripherals) via the MOVX instruction. Refer to Section
