DESCRIPTION
|
|
|
|
This file contains address space descriptor definitions for the VME bus.
|
|
|
|
Note that address space descriptors above 0x3f have already been assigned
|
|
to other busses, and additional address space descriptors should be
|
|
added only after consulting the appropriate header files and allocating
|
|
the next available descriptor.
