50 / 449 page  50 ATmega640/1280/1281/2560/2561 2549K–AVR–01/07 Power Management and Sleep Modes 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. Sleep Modes Fi gure 20 on page 37 presents the different clock systems in t h e ATmega640/1280/1281/2560/2561, and their distribution. The figure is helpful in select- ing an appropriate sleep mode. Table 24 shows the different sleep modes and their wake-up sources. Notes: 1. Only recommended with external crystal or resonator selected as clock source. 2. If Timer/Counter2 is running in asynchronous mode. 3. For INT7:4, only level interrupt. To enter any of the sleep modes, the SE bit in “SMCR – Sleep Mode Control Register” on page 54 must be written to logic one and a SLEEP instruction must be executed. The SM2, SM1, and SM0 bits in the SMCR Register select which sleep mode will be acti- vated by the SLEEP instruction. See Table 25 on page 54 for a summary. 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 con- tents 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. Table 24.
