Instruction Timing
Table 2-10 lists execution times for MOVE.{B,W} instructions.
Table 2-11 lists timings for MOVE.L.
Table 2-12 gives execution times for MOVE.L instructions accessing program-visible
registers of the MAC unit, along with other MOVE.L timings. Execution times for moving
contents of the ACC or MACSR into a destination location represent the best-case scenario
when the store instruction is executed and there are no load or MAC or MSAC instruction
