R01UH0330EJ0200 Rev.2.00 846
Dec 13, 2013
Table 29-5. Operation List (10/17)
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 code flash memory is accessed, or when the data flash memory is
accessed by an 8-bit instruction.
3. 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.
