description: The Integrator/AP is a prototyping platform and as such has a
|
|
site for stacking up to four logic modules (LM) designed specifically for
|
|
use with this platform. A special system controller register can be read to
|
|
determine if a logic module is connected at index 0, 1, 2 or 3. The logic
|
|
module connector is described in this binding. The logic modules per se
|
|
then have their own specific per-module bindings and they will be described
|
|
as subnodes under this logic module extension bus.

description: Nodes on the Logic Module bus represent logic modules
|
|
and are named with bus. The first module is at 0xc0000000, the second
|
|
at 0xd0000000 and so on until the top of the memory of the system at
|
|
0xffffffff. All information about the memory used by the module is
|
|
in ranges and dma-ranges.
