CMG-DM24S12AMS Operator's guide
The modular design of the system takes advantage of the processor's
paged structure: each module is designed to occupy its own separate
page, with a dedicated I/O function. Thus any module can simply be
added to the system at any available page when it is required. Each
module includes 32k of RAM which is used for data buffering and
workspace for the module’s software.
