11. Low Power Consumption (Standby) Modes
• The power consumption of F2MC-16LX devices can be reduced by various settings that control the operating
clock selection.
• Functions of each CPU operation mode
CPU Operation
Clock
Operation
Mode
Function
The CPU and peripheral functions operate using the oscillation clock (HCLK)
multiplied by the PLL circuit.
Normal Run
Sleep
The peripheral functions only operate using the oscillation clock (HCLK) mul-
tiplied by the PLL circuit.
PLL clock
The timebase timer only operates using the oscillation clock (HCLK) multi-
plied by the PLL circuit.
Pseudo-clock
Stop
The oscillation clock is stopped and the CPU and peripherals halt operation.
The CPU and peripheral functions operate using the oscillation clock (HCLK)
divided into 2.
Normal Run
Main clock
The peripheral functions only operate using the oscillation clock (HCLK) di-
vided into 2.
Sleep
Stop
The oscillation clock is stopped and the CPU and peripherals halt operation.
CPU intermittent
operation
The oscillation clock (HCLK) divided into 2 operates intermittently for fixed
time intervals.
