C8051F340/1/2/3/4/5/6/7
CIP-51 Instruction Set Summary, which includes the mnemonic, number of bytes, and number of clock
cycles for each instruction.
9.1.2. MOVX Instruction and Program Memory
The MOVX instruction is typically used to access external data memory (Note: the C8051F340/1/2/3/4/5/6/
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-programma-
ble 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 “12. Flash Mem-
ory” on page 109 for further details.
