SDL POK Example
Introduction
This example demonstrates the usage of the POK modules. The example shows how to listen for POK error events using the ESM, and also forcing an error in order to demonstrate application notification of overvoltage and undervoltage events.
The example demonstrates:
* Undervoltage event detection
* Overvoltage event detection

Steps to Run the Example
When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)
Launch a CCS debug session and run the executable, see CCS Launch, Load and Run
