Hi Parth Modi
If you checked the chapter 7 of the Reference manual you can find the Power Management functionality description for this MCU, you can find from chip power modes to Power modes transitions.
Also I recommend you to check the application note AN4470 and AN4503, These documents shows how to use the power management systems and they provide use case examples.
Finally you can check the document: Power Management on Kinetis MCUs: LLS and VLLS modes
This document is based in KDS IDE, but it has a baremetal examples that can be implemented in IAR. It uses FRDM-KL26Z but same principle applies to other Kinetis families.
Hope this information help you.
Have a great day,
Jorge Alcala
