BITS DESCRIPTIONS

[31:0] CURRENT_SRC_ADDR

The 32-bit Current Source Address indicates the source

address where the GDMA transfer is just occurring.

During a block transfer, the GDMA determines the

successive source addresses by adding to or subtracting

from the source base address. Depending on the settings

you make to the control register, the current source

address will remain the same or will be incremented or

decremented.
