LP-MSPM0G3507: About the behavior of TIMG0_IRQHandler

Part Number: LP-MSPM0G3507
Other Parts Discussed in Thread: MSPM0G3507

Hello.

I am using the "MSPM0G3507 LaunchPad Development Kit" to check the operation of timer interrupts.
When I executed the sample code "wwdt_window_mode_periodic_reset",
After executing "TIMG0_IRQHandler", "while(1)" in "main" was not executed.
What could be the cause?

1. You code is for timer, not for wtchdog. Can you double check?

2. Can you press the stop button to see where is the PC now?

The "timx_timer_mode_periodic_standby_LP_MSPM0G3507_nortos_ticlang" example worked fine for me.

Hello.

Thank you for your reply.
By commenting out "DL_SYSCTL_enablesSleepOnExit();" enclosed in blue,
The process inside the while loop enclosed in red is now executed.

What kind of processing does "DL_SYSCTL_enablesSleepOnExit()" do?
