CC1110F32 Interrupt Flags not clearing

Hi there!

I'm using a SmartRFCC1110-868 kit and IAR to evaluate the CC1110 SoC.

I'm having problems with some interrupt flags, specifically I can't clear them and the CPU vectors to the ISR non-stop.

Here are my code snippets. The bitfields are made by me because I didn't like IAR's definitions in the I/O file.

I have checked the assember listing and the code does try to clear the bits I need, but they stay set.

I have tried various approaches to look on the subject, breaking inside the ISR, halting in random locations, etc.

Once the CPU has vectored to the ISR, the flags stay set.

Thanks!

Edit: I should mention that I am talking about IRCON.T3IF  and TIMIF.T3OVFIF, shown on the ISR function.
