CH1_SAR
The starting source address is programmed by 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 source 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.
