Hi, I'm using chained DMA with SPORT1 on the ADSP-21479. I'm trying to generate an interrupt at the end of the DMA sequence. The SPORT is functioning and the DMA controller is loading memory as expected. The PCI bit is set and I use the interrupt() function to enable the interrupt and specify the function to serve as the ISR. I can see that the P3I bit is set in both IMASK and IMASKP registers, but my ISR is not executing. Suggestions? Thanks, Bob.
