+    Divide the D10V's 64k data space into four 16k segments:
+    0x0000 -- 0x3fff, 0x4000 -- 0x7fff, 0x8000 -- 0xbfff, and 
+    0xc000 -- 0xffff.
+ 
+    On the TS2, the first two segments (0x0000 -- 0x3fff, 0x4000 --
+    0x7fff) always map to the on-chip data RAM, and the fourth always
+    maps to I/O space.  The third (0x8000 - 0xbfff) can be mapped into
+    unified memory or instruction memory, under the control of the
+    single DMAP register.
+ 
+    On the TS3, there are four DMAP registers, each of which controls
+    one of the segments.  */
