ATmega128RFA1
an external level interrupt on INT7:4 or a pin change interrupt can wakeup the MCU
from ADC Noise Reduction mode.
When the SM2:0 bits are written to 010, the SLEEP instruction makes the MCU enter
Power-down mode. In this mode, the 16 MHz crystal oscillator is stopped (if selected by
CKSEL fuses), while the external interrupts, the 2-wire Serial Interface, and the
Watchdog continue operating (if enabled). Only an External Reset, a Watchdog Reset,
a Brown-out Reset, 2-wire Serial Interface address match, an external level interrupt on
INT7:4, an external interrupt on INT3:0, a pin change interrupt, or a symbol counter
interrupt can wake up the MCU. This sleep mode basically halts all generated clocks,
allowing operation of asynchronous modules only.
Note that if a level triggered interrupt is used for wake-up from Power-down mode, the
changed level must be held for some time to wake up the MCU. Refer to section
"External Interrupts" on page 218
When waking up from Power-down mode, there is a delay from the wake-up condition
occurs until the wake-up becomes effective. This allows the clock to restart and become
stable after have been stopped. The wake-up period is defined by the same CKSEL
Fuses that define the Reset Time-out period, as described in chapter
and Clock Options" on page
When the SM2:0 bits are written to 011, the SLEEP instruction makes the MCU enter
Power-save mode. This mode is identical to Power-down, with one exception:
If Timer/Counter2 is enabled, it will keep running during sleep. The device can wake up
from either Timer Overflow or Output Compare event from Timer/Counter2 if the
corresponding Timer/Counter2 interrupt enable bits are set in TIMSK2, and the Global
Interrupt Enable bit in SREG is set. If Timer/Counter2 is not running, Power-down mode
is recommended instead of Power-save mode.
The Timer/Counter2 can be clocked both synchronously and asynchronously in Power-
save mode. If the Timer/Counter2 is not using the asynchronous clock, the
Timer/Counter Oscillator is stopped during sleep. If the Timer/Counter2 is not using the
synchronous clock, the clock source is stopped during sleep. Note that even if the
synchronous clock is running in Power-save, this clock is only available for the
Timer/Counter2. Timer/Counter2 operation is described in detail in section
Timer/Counter2 with PWM and Asynchronous Operation" on page
When the SM2:0 bits are 110 and the crystal oscillator of the radio transceiver 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.
When the SM2:0 bits are 111 and the crystal oscillator of the radio transceiver is
selected, the SLEEP instruction makes the MCU enter Extended Standby mode. This
mode is identical to Power-save mode with the exception that the oscillator is kept
running. From Extended Standby mode, the device wakes up in six clock cycles.
