Sleep Modes
The CPU and affected modules are restarted when the sleep mode is exited. This occurs when
an interrupt triggers. Note that even if an interrupt is enabled in sleep mode, it may not trigger if
the source module is not clocked.
The following sleep modes are supported. These are detailed in
The power level of the internal voltage regulator is also adjusted according to the sleep mode to
reduce the internal regulator power consumption.
There are two types of wake up sources from sleep, synchronous and asynchronous. Synchro-
nous wake up sources are any non-masked interrupt. Asynchronous wake up sources are AST,
WDT, external interrupts from EIC, external resetor any asynchronous wake up enabled in the
AWEN (Asynchronous Wake Up Enable) register. The valid wake up sources for each sleep
mode is detailed in
Table 7-3.
• Idle: The CPU is stopped, the rest of the chip is operating.
• Frozen: The CPU and HSB modules are stopped, peripherals are operating.
• Standby: All synchronous clocks are stopped, but the clock sources are running, allowing
• Stop: As Standby, but oscillators, and other clock sources are stopped. 32KHz (if enabled),
• DeepStop: All synchronous clocks and clock sources are stopped. 32KHz oscillator can run if
• Static: All clock sources, including RC oscillator are stopped. 32KHz oscillator can run if
