Figure 7. Example Address Memory Map
The following shows an example illustrating the address translation used in each VLYNQ module.
Address bits [31:26] are not used for address translation to remote devices on the DM644x device.
Table 3 illustrates address map register configuration when the DM644x device is transmitting data to the
remote device.
