Ahhrg! Again, my microcontroller stopped in an interrupt. And I have no clue why?
Using Processor Expert in MCU10 is a great thing as it takes care about the vector table. Usually the default settings for code generation are fine, but not in my case here. If you run into a spurious and unexpected interrupt, you stop in the Cpu_Interrupt() handler:

I use a Intel processor to write this text, and this processor is is using Little Endian for the byte order. This is about Endian, not Indian :-).
Many processors I have programmed were Big Endians. With the addition of Freescale Kinetis (an ARM Cortex M4) and DSC in MCU10.2, I have a daily mixture with Big Endian (S08, ColdFire, …) and Little Endian (DSC and Kinetis).
The term “endian” is described nicely in the IEN 137 written 1980 by Danny Cohen:
“ON HOLY WARS AND A PLEA FOR PEACE“.

I just have run across a problem: I received a project for the S08QE128, and when I started a debug session with MCU10.2, the debugger was showing “no source available”. Ahhrg. Something must be wrong…
No Source Available?
Well, at least I can debug on assembly level. But this is not the point. I have the sources, but somehow the debugger does not find them?
