The wake-up events can be asynchronous or synchronous. Synchronous wake-up events require the 32-kHz clock or the system clock to be active, while asynchronous wake-up events do not require an active clock.
The Modules Attributes subsection of each clock domain in Section 3.6, Clock Management Functional Description, describes the wake-up capability support for each module of the corresponding power domain.
While the device is in STANDBY mode, additional asynchronous wakeup events from other domains are able to wake up the device.
Table 3-421 identifies which modules in which power domains can be configured to generate a wake-up while the device is in a low-power mode.
