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 internal voltage regulator is also adjusted according to the sleep mode in order to reduce its
power consumption.
There are two types of wake up sources from sleep, synchronous and asynchronous. Synchro-
nous wake up sources are all non-masked interrupts. Asynchronous wake up sources are AST,
WDT, external interrupts from EIC, external reset, external wake-pin (WAKE_N), and all asyn-
chronous walk-ups enabled in the Asynchronous Wake Up Enable (AWEN) register. The valid
wake up sources for each sleep mode is detailed in
