RL78/G1H CHAPTER 30 INSTRUCTION SET
R01UH0575EJ0120 Rev. 1.20 Page 855 of 920
Dec 22, 2016
Note 1. Number of CPU clocks (fCLK) when the internal RAM area, SFR area, or extended SFR area is accessed, or when no
data is accessed.
Note 2. Number of CPU clocks (f
CLK) when the code flash memory is accessed, or when the data flash memory is accessed by
an 8-bit instruction.
Note 3. This indicates the number of clocks “when condition is not met/when condition is met”.
Note 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.
