You did not clear the interrupt in the TMR component. Depending on what kind of timer you use (UDB or TCPWM) you need to read the TMR status or explicitly clear the interrupt in your handler.
Next time will you please post your complete project so that we all can have a look at all of your settings. To do so, use
Creator->File->Create Workspace Bundle (minimal)
and attach the resulting file.
Thank you it works!!!!
Forgot about it.
I will attach the complete code next time.
