Sleep Modes
BOD Disable
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.
When enabled, the Brown-out Detector (BOD) actively monitors the power supply voltage during
the sleep periods. To further save power, it is possible to disable the BOD in some sleep modes.
See
Figure 4-1 on page 23

sleep modes, their wake up sources and BOD disable ability.
Table 5-1.
Note:
To enter any of the four sleep modes, the SE bit in SMCR must be written to logic one and a
SLEEP instruction must be executed. The SM1, and SM0 bits in the SMCR Register select
which sleep mode (Idle, ADC Noise Reduction, Power-down, or Power-save) 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.
When the Brown-out Detector (BOD) is enabled by BODLEVEL fuses,
the BOD is actively monitoring the power supply voltage during a sleep period. To save power, it
is possible to disable the BOD by software for some of the sleep modes, see
sleep mode power consumption will then be at the same level as when BOD is globally disabled
by fuses. If BOD is disabled in software, the BOD function is turned off immediately after enter-
