This register is used to enable the DW_axi_dmac, which must be done before any channel
activity can begin. This register also contains global interrupt enable bit.

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

DMAC_EN
|
This bit is used to enable the DW_axi_dmac. - 0: DW_axi_dmac disabled - 1: DW_axi_dmac enabled NOTE: If this bit DMAC_EN bit is cleared while any channel is still active, then this bit still returns 1 to indicate that there are channels still active until DW_axi_dmac hardware has terminated all activity on all channels, at which point this bit returns zero (0).
