Wake-up Subsystem (WKUPSS) is defined as an isolated domain to control operating states of the device. It supports low-power modes of operations and safety precautions during power transitions. Located in the WKUPSS are dedicated subsystems for device management and security functions.
Figure 1-4 shows the block diagram of the device WKUP domain.
The supported set of features and peripherals is device part number dependent. For more information, see the device-specific Datasheet.
