9.3.3 GDMA SOURCE/DESTINATION ADDRESS REGISTERS

The GDMA source/destination address registers contain the 32-bit source/destination addresses for GDMA
channels 0, 1, 2, 3, 4, and 5. These address registers cover the whole external memory space, including the
special purpose registers. You have to reference the memory map of the S3C2501X (Chapter 4) when you want
to set these address registers. Depending on the settings you make to the GDMA control register (DCON), the
source or destination addresses will either remain the same, or they will be increased or decreased. When DCON
MODE [3:1] is HUART RX mode (HUART to memory, "011") or DES OUT mode (DES to memory, "101"), the
DSAR register doesn't care. Also, when DCON MODE [3:1] is HUART TX mode (HUART from memory, "010") or
DES IN mode (DES from memory, "100"), the DDAR register doesn't care.
