Summary of Move Instructions (1/3)
Notes: 1. A shaded cell denotes an instruction in the C51 Architecture.
2. Extended memory addressed is in the region specified by DPXL (reset value = 01h).
3. If this instruction addresses external memory location, add N+1 to the number of
states (N: number of wait states).
4. If this instruction addresses external memory location, add N+2 to the number of
states (N: number of wait states).
