EDMA channel 15 services the incoming data stream of McASP. The source address is set to that of the receive serializer buffer, and the destination address is set to the first element of the data block. Because there are two data channels being serviced, A and B, they are to be located separately within the L2 SRAM.
To facilitate continuous operation, a copy of the PaRAM set for the channel is placed in PaRAM set 64. The LINK option is set and the link address is provided in the PaRAM set. Upon exhausting the channel 15 parameter set, the parameters located at the link address are loaded into the channel 15 parameter set and operation continues. This function continues throughout device operation until halted by the CPU.
