I/O Process Image Map
An IO module may have three types of data as I/O data, configuration parameter, and
memory register. The data exchange between network adapter and IO modules is done by
means of an I/O process image data by RSTi bus protocol.
The following figure shows the data flow between network adapter and IO modules.
