XMEGA A [MANUAL]
8077I–AVR–11/2012
Table 8-1.
Active clock domains and wake-up sources in the different sleep modes.
The wake-up time for the device is dependent on the sleep mode and the main clock source. The startup time for the
system clock source must be added to the wake-up time for sleep modes where the system clock source is not kept
running. For details on the startup time for the different oscillator options, refer to “System Clock and Clock Options” on
page 79.
The content of the register file, SRAM and registers are kept during sleep. If a reset occurs during sleep, the device will
reset, start up, and execute from the reset vector.
8.3.1
Idle Mode
In idle mode the CPU and nonvolatile memory are stopped (note that any ongoing programming will be completed), but
all peripherals, including the interrupt controller, event system and DMA controller are kept running. Any enabled
interrupt will wake the device.
8.3.2
Power-down Mode
In power-down mode, all clocks, including the real-time counter clock source, are stopped. This allows operation only of
asynchronous modules that do not require a running clock. The only interrupts that can wake up the MCU are the two-
wire interface address match interrupt and asynchronous port interrupts.
8.3.3
Power-save Mode
Power-save mode is identical to power down, with one exception. If the real-time counter (RTC) is enabled, it will keep
running during sleep, and the device can also wake up from either an RTC overflow or compare match interrupt.
8.3.4
Standby Mode
Standby mode is identical to power down, with the exception that the enabled system clock sources are kept running
while the CPU, peripheral, and RTC clocks are stopped. This reduces the wake-up time.
8.3.5
Extended Standby Mode
Extended standby mode is identical to power-save mode, with the exception that the enabled system clock sources are
kept running while the CPU and peripheral clocks are stopped. This reduces the wake-up time.
