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.

Table 3. Address Translation Example (Single Mapped Region)

Register	DM644x VLYNQ Module	Remote VLYNQ Module
TX Address Map	0000 : 0000h	Do not care
RX Address Map Size 1	Do not care	0000 : 0100h
RX Address Map Offset 1	Do not care	0800 : 0000h
