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