If there are wait states, (i.e., assumption 4 is not applicable) then to each 1-word instruction timing a "+ap"
term should be added and to each 2-word instruction a "+(2 * ap)" term should be added to account for the
program memory wait states spent to fetch an instruction word to fill the pipeline.

Figure A-11 MOVEM Timing Summary
If there are wait states, (i.e., assumption 4 is not applicable) then to each 1-word instruction timing a "+ap"
term should be added and to each 2-word instruction a "+(2 * ap)" term should be added to account for the
program memory wait states spent to fetch an instruction word to fill the pipeline.
Note that the "ap" term present in Figure A-11 for the P Memory Move entry represents the wait states
spent when accessing the program memory during DATA read or write and does not refer to instruction
fetches.
