Abstract
A system having a serial interface for a codec containing multiple converters employs a local memory and a DMA (direct memory access) unit for transferring data to and from the codec. To distinguish data associated with each converter, a separate DMA channel is assigned to each converter. Data is transmitted in frames having fields associated with different DMA channels to avoid confusion regarding the source or destination of data.
