Active Clock Domains and Wake-up Sources in the Different Sleep Modes.
Active Clock Domains
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 consump-
tion to the application’s requirements.

To enter any of the sleep modes, the SE bit in

SM0 bits in the SMCR Register select which sleep mode will be activated by the SLEEP instruc-
tion. 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.
When the SM2:0 bits are written to 000, the SLEEP instruction makes the MCU enter Idle mode,
stopping the CPU but allowing the SPI, USART, Analog Comparator, ADC, 2-wire Serial Inter-
face, Timer/Counters, Watchdog, and the interrupt system to continue operating. This sleep
