The tiny low power manager module has been designed to facilitate the power optimization within an application. [file:overview.jpg] The application shall configure the LPM module to select the right low power mode compatible with his current state. When the application has no action to perform, it enters the Idle task which is used to execute the low power allowed by the LPM settings.
The module provides the capabilities to drive three different LPMMode:
- Sleep mode: WFI or WFE mode where any incoming interrupt/event shall exit the mode.
- Stop mode: this mode must be allowed by each part of the application according their HW restriction (for example during a DMA transfer STOP mode must be forbidden due to incompatibility between DMA and Stop mode)
- Off mode: Default low power mode selected after the initialization, the exit of this mode is a platform reset and the application context shall be restored.
The LPM configuration consists for each LPMActor to define the LPM mode allowed by the actor.
