m: RW0 value (counter value)

n: Loop count

*1: 5 when RW0 is 0, 4 + 7 × (RW0) for count out, and 7 × n + 5 when match occurs

*2: 5 when RW0 is 0, 4 + 8 × (RW0) in any other case

*3: (b) × (RW0) + (b) × (RW0) when accessing different areas for the source and destination, calculate (b) separately

for each.

*4: (b) × n

*5: 2 × (RW0)

*6: (c) × (RW0) + (c) × (RW0) when accessing different areas for the source and destination, calculate (c) separately

for each.

*7: (c) × n

*8: 2 × (RW0)

Note: For an explanation of “(a)” to “(d)”, refer to Table 4, “Number of Execution Cycles for Each Type of Addressing,”

and Table 5, “Correction Values for Number of Cycles Used to Calculate Number of Actual Cycles.”
