• BLOCK_TS: Block Transfer Size
When the DMAC is flow controller, this field is written by the user before the channel is enabled to indicate the block size.
The number programmed into BLOCK_TS indicates the total number of single transactions to perform for every block
transfer. The width of the single transaction is determined by DMAC_CTLx.SRC_TR_WIDTH.
• DONE: Done Bit
Software can poll the LLI DMAC_CTLx.DONE bit to see when a block transfer is complete. The LLI DMAC_CTLx.DONE bit
should be cleared when the linked lists are setup in memory prior to enabling the channel.
