Problems Using Iterrupts HC908GP32

Hello

I’m having some problems using the interrupts of the MC68HC908GP32, I had made easy example using the interrupts, but they are not working, can somebody help me?

Here is the code I used, is in assembly.

By the way, I will appreciate an understanding answer, because English is not my first language.

Thanks

I have not reproduced such problem on HW and I think your project works properly therefore it is probably HW issue. Since you have enabled the PLL clock in your project, you should check the connection of the filter on pin 3.

More information about filter connection can be found in chapter "5.3.9 CGM External Connections" in MC68HC908GP32 datasheet.
