When SM2..0 is 001, the SLEEP instruction will put the MCU into noise suppression mode. In this mode, the CPU stops running, while the ADC, external interrupts, two-wire interface address configuration, timer/counter 0 and watchdog continue to work. This sleep mode only stops clkI/O, clkCPU and clkFLASH, and other clocks continue to work. This mode improves the noise environment of the ADC and makes the conversion accuracy higher. When the ADC is enabled, entering this mode will automatically start an AD conversion. The ADC conversion end interrupt, external reset, watchdog reset, BOD reset, two-wire interface address match interrupt, timer/counter 0 interrupt, SPM/EEPROM ready interrupt, external interrupt INT7:4, or external interrupt INT3:0 can wake up the MCU from ADC noise suppression mode.
