CH4_DAR
The starting destination address is programmed by the software before the DMA channel is enabled, or by an LLI update before the start of the DMA transfer.
While the DMA transfer is in progress, this register is updated to reflect the destination address of the current AXI transfer.

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.
