Processor Expert provides possibility to switch between processor modes by providing concept of “operation modes”.
The CPU component provides a function SetOperationMode that can be called to select one the following general modes:
These modes are mapped to the platform specific modes of the chip. By switching to WAIT/SLEEP/STOP modes when possible (for example no computation is done for a while), it's possible to achieve a lower consumption of the whole chip.
The following table shows an example of the operation modes mapping for Kinetis L that shows the state of the core, bus and recovery method for each mode:
The Very low power mode option is available in Clock configurations of CPU properties (see below), i.e. the selection of the power mode is done by combination of the SetOperationMode and SetClockConfiguration methods.
The exact mapping of the DOM_xxx options can be configured in the CPU component inspector (the Advenced view has be enabled). For example the DOM_SLEEP can be mapped to normal stop mode, very low power stop, partial stop 1 or partial stop 2 of Kinetis L.
After many attempts to understand Kinetis low power options with Processor Expert, I finally found this chart. Now it is clear. Thank you!
I don't see a Very Low Power item under configuration on my chip.
