RL78/F13, F14 CHAPTER 33 INSTRUCTION SET
R01UH0368EJ0210 Rev.2.10 1678
Dec 10, 2015
Table 33-5. Operation List (18/18)
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”.
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.
