*1: 5 when RW0 is 0, 4 + 7 x (RW0) when the counter expires, or 7n + 5 when a match occurs
*2: 5 when RW0 is 0; otherwise, 4 + 8 x (RW0)
*3: (b) x (RW0) + (b) x (RW0) When the source and destination access different areas, calculate the (b) item individually.
*4: (b) x n
*5: 2 x (RW0)
*6: (c) x (RW0) + (c) x (RW0) When the source and destination access different areas, calculate the (c) item individually.
*7: (c) x n
Note:
m: RW0 value (counter value), n: Loop count
See Table A.5-1 "Execution cycle counts in each addressing mode" and Table A.5-2 "Cycle count
correction values for counting execution cycles" for information on (a) to (d) in the table.
