the Analog Comparator can be powered down by setting the ACD bit in “ACSR – Analog Com-
parator Control and Status Register” on page 129. This will reduce power consumption in Idle
mode. If the ADC is enabled, a conversion starts automatically when this mode is entered.
7.1.2
ADC Noise Reduction Mode
When the SM[1:0] bits are written to 01, the SLEEP instruction makes the MCU enter ADC
Noise Reduction mode, stopping the CPU but allowing the ADC, the external interrupts, and the
Watchdog to continue operating (if enabled). This sleep mode halts clk
I/O, clkCPU, and clkFLASH,
while allowing the other clocks to run.
This improves the noise environment for the ADC, enabling higher resolution measurements. If
the ADC is enabled, a conversion starts automatically when this mode is entered. Apart form the
ADC Conversion Complete interrupt, only an External Reset, a Watchdog Reset, a Brown-out
Reset, an SPM/EEPROM ready interrupt, an external level interrupt on INT0 or a pin change
interrupt can wake up the MCU from ADC Noise Reduction mode.
7.1.3
Power-Down Mode
When the SM[1:0] bits are written to 10, the SLEEP instruction makes the MCU enter Power-
down mode. In this mode, the Oscillator is stopped, while the external interrupts, and the Watch-
dog continue operating (if enabled). Only an External Reset, a Watchdog Reset, a Brown-out
Reset, an external level interrupt on INT0, or a pin change interrupt can wake up the MCU. This
sleep mode halts all generated clocks, allowing operation of asynchronous modules only.
7.1.4
Standby Mode
When the SM[1:0] bits are 11 and an external crystal/resonator clock option is selected, the
SLEEP instruction makes the MCU enter Standby mode. This mode is identical to Power-down
with the exception that the Oscillator is kept running. From Standby mode, the device wakes up
in six clock cycles.
7.2
Software BOD Disable
When the Brown-out Detector (BOD) is enabled by BODLEVEL fuses (see Table 19-4 on page
159), the BOD is actively monitoring the supply voltage during a sleep period. In some devices it
is possible to save power by disabling the BOD by software in Power-Down and Stand-By sleep
modes. The sleep mode power consumption will then be at the same level as when BOD is glob-
ally disabled by fuses.
If BOD is disabled by software, the BOD function is turned off immediately after entering the
sleep mode. Upon wake-up from sleep, BOD is automatically enabled again. This ensures safe
operation in case the V
CC level has dropped during the sleep period.
When the BOD has been disabled, the wake-up time from sleep mode will be approximately
60s to ensure that the BOD is working correctly before the MCU continues executing code.
BOD disable is controlled by the BODS (BOD Sleep) bit of MCU Control Register, see “MCUCR
– MCU Control Register” on page 36. Writing this bit to one turns off BOD in Power-Down and
Stand-By, while writing a zero keeps the BOD active. The default setting is zero, i.e. BOD active.
Writing to the BODS bit is controlled by a timed sequence and an enable bit, see “MCUCR –
