Standby Mode
Power Reduction Register
When the SM2..0 bits are 110 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.
Table 6-19.
Notes:
The Power Reduction Register, PRR, provides a method to stop the clock to individual periph-
erals to reduce power consumption. The current state of the peripheral is frozen and the I/O
registers can not be read or written. Resources used by the peripheral when stopping the
clock will remain occupied, hence the peripheral should in most cases be disabled before
stopping the clock. Waking up a module, which is done by clearing the bit in PRR, puts the
module in the same state as before shutdown.
Module shutdown can be used in Idle mode and Active mode to significantly reduce the overall
power consumption. See
sleep modes, the clock is already stopped.

1. Only recommended with external crystal or resonator selected as clock source.
2. If Timer/Counter2 is running in asynchronous mode.
3. For INT1 and INT0, only level interrupt.
