Sleep Modes
Idle Mode
The high performance and industry leading code efficiency makes the AVR microcontrollers an
ideal choise for low power applications. In addition, sleep modes enable the application to shut
down unused modules in the MCU, thereby saving power. The AVR provides various sleep
modes allowing the user to tailor the power consumption to the application’s requirements.

the different sleep modes and their wake up sources.
Table 7-1.
Note:
To enter any of the four sleep modes, the SE bits in SMCR must be written to logic one and a
SLEEP instruction must be executed. The SM2:0 bits in the SMCR register select which sleep
mode (Idle, ADC Noise Reduction, Standby or Power-down) will be activated by the SLEEP
instruction. See
If an enabled interrupt occurs while the MCU is in a sleep mode, the MCU wakes up. The MCU
is then halted for four cycles in addition to the start-up time, executes the interrupt routine, and
resumes execution from the instruction following SLEEP. The contents of the Register File and
SRAM are unaltered when the device wakes up from sleep. If a reset occurs during sleep mode,
the MCU wakes up and executes from the Reset Vector.
Note that if a level triggered interrupt is used for wake-up the changed level must be held for
some time to wake up the MCU (and for the MCU to enter the interrupt service routine). See
“External Interrupts” on page 37
When bits SM2:0 are written to 000, the SLEEP instruction makes the MCU enter Idle mode,
stopping the CPU but allowing the analog comparator, timer/counter, watchdog, and the inter-
rupt system to continue operating. This sleep mode basically halts clk
allowing the other clocks to run.
Idle mode enables the MCU to wake up from external triggered interrupts as well as internal
ones like the timer overflow. If wake-up from the analog comparator interrupt is not required, the
