RL78/G13 CHAPTER 28 INSTRUCTION SET
R01UH0146EJ0100 Rev.1.00 967
Sep 22, 2011
Table 28-5. Operation List (6/17)
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. Except rp = AX
4. Except r = A
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.
