6.1.2. MOVX Instruction and Program Memory
The MOVX instruction is typically used to access external data memory (Note: the C8051F326/7 does not
support off-chip data or program memory). In the CIP-51, the MOVX write instruction is used to accesses
external RAM (XRAM) and the on-chip program memory space implemented as re-programmable Flash
memory. The Flash access 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 Section “8. Flash Memory” on page 63
for further details.
