Figure 3-3 shows the block diagram for the AT-MIO-16E-10 and
AT-MIO-16DE-10.
Figure 3-3. AT-MIO-16E-10 and AT-MIO-16DE-10 Block Diagram
The primary differences between the AT-MIO-16E-10 and the
AT-MIO-16DE-10 are in the 8255 DIO port, which is not present on
the AT-MIO-16E-10, and the I/O connector.
