Hi All, I am working on TEB6416. I am facing a very wierd problem in the EDMA interrupt. After completion of very first DMA the CPU services the EDMA ISR. In the ISR, I make the corresponding bit in CIPR register as 0. For all subsequent EDMA transfer completes, CPU doesn't goes to the ISR. I have enabled interuppt for other EDMA transfers also and I have given Interuppt threshold as 6. The subsequent EDMA transfers are proper though. Thanks in advance for any help. Regards Kismat

Hi, Kismat Singh, To configure the EDMA for any channel (or QDMA request) to interrupt the CPU: 1. Set CIEn to '1' in the CIER 2. Set TCINT to '1' in channel options 3. Set Transfer Complete Code to n in channel options And when you want to clear CIPR bits you should writing a '1' to the relevant bits, writing a ‘0’ has no effect.
