ADuC841 XRAM as circular buffer in DMA mode

Question asked by avalecha on Nov 17, 2011

How can we organize circular buffer in the internal XRAM of ADuC841. Since we have to preconfigure the 'stop location', how can we reconfigure xram address while runing the current ADC DMA sequence. I want to capture an event which is synchronized with an external trigger through INT0 with pre and post trigger information.
