The PDMA channel will remain idle until a pulse is detected on the associated input DMA request event pin. Once the pulse is detected, the DMA will sequentially issue a total of 'Y' parameter reads of 'X' parameter bytes from the data FIFO address specified for the channel. Each read that the DMA performs will be a single 'X' element in size (no large bursts). Once the total specified number of transactions has been completed the channel will return to an idle state and wait until it is triggered again. The read transfers that are performed will be accomplished as quickly as possible given availability of data in the Rx channelized FIFO and given the arbitration that may occur as a result of other channels also using the same read unit.
