Notes 1. Number of CPU clocks (f
when no data is accessed.
2. Number of CPU clocks (f
3. This indicates the number of clocks "when condition is not met/when condition is met".
4. n indicates the number of register banks (n = 0 to 3).
Remark Number of clock is when program exists in the internal ROM (flash memory) area. If fetching the instruction
from the internal RAM area, the number becomes double number plus 3 clocks at a maximum.
