Can more than one device do DMA transfers simultaneously on a single PPI interface?
I need to collect data from two AD7606 ADCs simultaneously using DMA and need to know if this will require a Blackfin with two PPI ports.
a DMA is mapped to a peripheral, not to a device attached to the peripheral.
The PPI has only one input (or output) at the same time, running two devices simultaneosly will end (in best case) in data corruption or mybe damage the part(s).
