CHAPTER 30 INSTRUCTION SET
Page 849 of 920
Note 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.
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.
Remark 1.
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.
Remark 2.
MACR indicates the multiplication and accumulation register (MACRH, MACRL).
