Table 28-5. Operation List (16/17)
Notes 1. Number of CPU clocks (f
CLK) when the internal RAM area, SFR area, or extended SFR area is accessed, or
when no data is accessed.
2. Number of CPU clocks (f
CLK) when the program memory area is accessed.
3. This indicates the number of clocks “when condition is not met/when condition is met”.
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.
