Introduction

This example demonstrates High and Low priority events received from the MCU_ESM through the application-registered callback. It also shows routing and clearing of events to the MCU_SAFETY_ERRORn pin.

This example displays setting up ESM to

* Enable/Disable input events to the ESM module for each ESM instance
* Registration of application callback for ESM error events for each ESM instance
* Designating input events as high priority or low priority for each ESM instance
* Designating direct pin routing to MCU_SAFETY_ERRORn pin for external monitor communication

Use Cases

Use Case	Description
UC-0	Configuration of High Priority ESM
UC-1	Configuration of Config Priority ESM
UC-2	Configuration of Low Priority ESM

Supported Combinations

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

Sample Output

Shown below is a sample output when the application is run,

ESM Example Application
 
TIMER_ESM_init: Init MCU ESM complete
 
ESM example init complete
  Any clear of MCU_SAFETY_ERRORn pin will first wait 10 usecs
  Minimum Time Interval is 2000 usecs
ESM timer initialization complete
 
Starting Test Case 0
 
Use Case 0 completed: Input Event Trigger = Step completed successfully,
                       Event Handler Complete = Step completed successfully,
                       MCU_SAFETY_ERRORn Pin Clear = Step completed successfully
 
Starting Test Case 1
 
Use Case 1 completed: Input Event Trigger = Step completed successfully,
                       Event Handler Complete = Step completed successfully,
                       MCU_SAFETY_ERRORn Pin Clear = Step completed successfully
 
Starting Test Case 2
 
Use Case 2 completed: Input Event Trigger = Step completed successfully,
                       Event Handler Complete = Step completed successfully,
                       MCU_SAFETY_ERRORn Pin Clear = Step completed successfully
