Channel 0 Useburst Set
Write to 1 to enable the useburst setting for this channel. Reading returns the useburst status. After the penultimate 2^R transfer
completes, if the number of remaining transfers, N, is less than 2^R then the controller resets the chnl_useburst_set bit to 0.
This enables you to complete the remaining transfers using dma_req[] or dma_sreq[]. In peripheral scatter-gather mode, if the
next_useburst bit is set in channel_cfg then the controller sets the chnl_useburst_set[C] bit to a 1, when it completes the DMA cycle
that uses the alternate data structure.
