[31:0] CURRENT_DST_ADDR

The 32-bit Current Destination Address indicates the
destination address where the GDMA transfer is just
occurring. During a block transfer, the GDMA determines
the successive destination addresses by adding to or
subtracting from the destination base address. Depending
on the settings you make to the control register, the current
destination address will remain the same or will be
incremented or decremented.
