Introduction

This example uses the WDT module in non reset mode to generate NMI Interrupt.

• The Watchdog interrupt is configured as a non-maskable interrupt and the user-defined callback function is registered.
• ESM module is configured with ESM Group 2 number and ESM NMI number to generate a non-maskable interrupt to the CPU.
• The callback function in the application handles the watchdog interrupt
• Make sure to confirm the following configuration in syscfg.
  WDT Reset Mode: trigger WDT interrupt

Using SDK with SysConfig

A GUI tool SysConfig is used to configure different modules and peripherals of the example. Using this tool, users can select and customize different modules and peripherals. The SysConfig tool will generate the code for initializing and configuring these modules. This configuration is saved to a file called example.syscfg for every example. To know more about how to use SDK with SysConfig, Visit this page

Using SDK with SysConfig

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
• Please select the UART port used for console as mentioned in Setup UART Terminal
