Hi to everyone;
 
I'm working on the driver developing of MCF52233, and using a M52233DEMO board, and Codewarrior 5.7. Up to now everithing has worked more or less fine, but while working on DTIM0 driver, a strange problem has appeared.:
 
-A after some seconds, the interrupt system of the MCU stops so any interrupt is working no more, if DTIM0 interrupt is enabled.
 
The MCU is still working because i can stop the program and run by step.
 
I have no idea why the interrupts stops to work suddenly. Does anyone has this problem???
 
Thanks a lot.
