DESCRIPTIONS
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.
