3:0 | flag | This register can be used to force rescan of buffer flags in any of the cmd-dma channels. The bit index decides the Channel number. Cmd-dma would rescan the buffer flag for matching condition and it executes the descriptor if it is ready. Hardware clears this register after generating the trigger event. |
