I'm using MPC5744C for my project. Currently, I'm trying to write data to ETIMER in user mode:

        ETIMER_0.CH[0].CNTR.R = 1000; //My code

But Machine trap is fired (status is below pic):

I turned off all MPU mechanism and check AIPS configuration and it is OK. But Trap still happen.

So, Can you help me to find out trap's source?

Which reason can fired this trap?

 

Thanks!
