power_manager#
Overview#
The power manager demo application demonstrates how to change power modes in the KSDK. Unlike the Power Mode Switch demo, which directly controls the target mode from the menu flow, this demo uses a notification framework to inform the application about the mode change. An application can register a callback to the notification framework; when the power mode changes, the callback function is called so the application can do something, such as closing the debug console before entering low power mode and opening the debug console after exiting low power mode.
When this demo runs, the power mode menu is shown in the debug console, where the user can set the MCU to a specific power mode. User can also set the wakeup source following the debug console prompts.
Tips: This demo is to show how the various power mode can switch to each other. However, in actual low power use case, to save energy and reduce the consumption even more, many things can be done including:
Disable the clock for unnecessary modules during low power mode. That means, programmer can disable the clocks before entering the low power mode and re-enable them after exiting the low power mode when necessary.
Disable the function for unnecessary part of a module when other part would keep working in low power mode. At the most time, more powerful function means more power consumption. For example, disable the digital function for the unnecessary pin mux, and so on.
Set the proper pin state (direction and logic level) according to the actual application hardware. Otherwise, there would be current leakage on the pin, which will increase the power consumption.
Other low power consideration based on the actual application hardware.

Keep JTAG pins open, don’t connect any debugger on it.
For low power purpose, the demo requires pad voltage supply to be fixed as follows: VDDIO_0: 1.8V (PMIC SW2_OUT using default setting 1.8V) VDDIO_1: 1.8V (PMIC SW2_OUT using default setting 1.8V) VDDIO_2: 1.8V (PMIC SW2_OUT using default setting 1.8V) VDDIO_3: 3.3V (PMIC LDO2_OUT using default setting 3.3V) VDDIO_4: 1.8V (PMIC SW2_OUT using default setting 1.8V) NOTE: Supplying wrong voltage on the pads is harmful to the device.

Keep J2 and J19 unconnected to avoid unintentional reset by IF_RST signal in full deep power down mode.
For low power purpose, the demo requires pad voltage supply to be fixed as follows: VDDIO_0: 1.8V (connecting JP20 1-2, and PMIC SW2_OUT using default setting 1.8V) VDDIO_1: 1.8V (connecting JP12 1-2, supply from PMIC SW2_OUT)) VDDIO_2: 3.3V (connecting JP27 1-2, and PMIC LDO2_OUT using default setting 3.3V) NOTE: By default, the demo allows wide voltage supply on VDDIO_1. To further reduce the leakage, Vdde1Range can be set to narrow range kPadVol_171_198. Special care should be taken that supplying wrong voltage on the pads is harmful to the device.
