Nested Interrupts on C2000

Herb

Is there any way of nesting interrupts without DSP/BIOS on the TMS320F2809? I am trying to get an ADC SEQ1INT ISR to preempt an ePWM1_INT ISR. Re-stated, I'd like the SEQ1INT interrupt to pre-empt the ePWM1_INT interrupt.

The EPWM1_INT interrupt occurs at a 50usec rate and the ADC SEQ1INT occurs at a 25usec rate in our system.

Hi Herb,

Please see the interrupt nesting info on this wiki page:
