QUESTION

I have a problem with interrupts on the Infineon C16x/ST10. I have enabled the interrupts by setting IEN=1 in the PSW register, but it seems that interrupts do not work. Are there any known problems?

ANSWER

To enable interrupts on the C16x and ST10 devices you must globally enable interrupts (IEN=1) AND you must enable the individual interrupt source. You must also enable the group and interrupt level for each interrupt source.

Take a look at the device databook and/or to the uVision2 Getting Started User's Guide, Chapter 9, Interrupts. There, the concept of interrupts is explained in detail.
