Because the translation records are larger in extended mode, the look-up table memory map changes, the transla-
tion record address calculations change, and the memory size calculations change. Figure 9 shows the new trans-
lation RAM memory map for 16-byte records when the device is configured for 16 or less PHY ports. When greater
than 16 PHY ports are used, the look-up table is shared between even and odd ports. Figure 10 shows this trans-
lation RAM memory map.
