Instruction Timing
MAC execution pipeline. In general, these store operations require only one cycle for
execution, but if they are preceded immediately by a load, MAC, or MSAC instruction, the
MAC pipeline depth is exposed and execution time is three cycles.
2.7.2 Execution Timings—One-Operand Instructions
Table 2-13 shows standard timings for single-operand instructions.
