DMA CONTROLLER  
S3C4510B  
DMA TRANSFER TIMING DATA  
Figure 9-8 provides detailed timing data for GDMA data transfers that are triggered by external DMA requests.  
Please note that read/write timing depends on which memory banks are selected.  
To access ROM banks, which is in multiplexing bus mode, by 4-data burst mode, refer to Figure A-1 and Figure  
A-2 of appendix A for read/write timing of ROM bank 5.
