Sleep Modes
ATtiny87/ATtiny167
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 dur-
ing the sleep periods. To further save power, it is possible to disable the BOD in some sleep
modes. See
Figure 4-1 on page 24
tribution. The figure is helpful in selecting an appropriate sleep mode.
different 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.
