3.2 Group Address Space
There are eight main address space segments that the GT-32090 decodes. The segments are DRAM, four AD
devices, PCMCIA, SIO devices, and Internal registers.
DRAM Address Space, Offset: 0x000
Device 0 Address Space, Offset: 0x004
Device 1 Address Space, Offset: 0x008
Device 2 Address Space, Offset: 0x00c
Boot Device Address Space, Offset: 0x010
