MOVE Instruction Execution Times
lists execution times for MOVE.{B,W} instructions;
lists timings for MOVE.L.
NOTE
For all tables in this section, the execution time of any instruction using the
PC-relative effective addressing modes is the same for the comparable
An-relative mode.
The nomenclature xxx.wl refers to both forms of absolute addressing, xxx.w
and xxx.l.
ET with {<ea> = (d16,PC)}
equals ET with {<ea> = (d16,An)}
ET with {<ea> = (d8,PC,Xi*SF)}
equals ET with {<ea> = (d8,An,Xi*SF)}
