I'm using the 72F324B in an application and trying to use Active Halt mode.

Most of the time the application enters and exits active halt mode correctly but randomly the cpu resets.

I can see from my trace that the preceding instruction is always HALT, then I see the reset vector fetch.

If I change the HALT to WFI it is reliable.

Has anyone had similar problems or any suggestions ?
