eral and memory resources. An ASCII terminal interface that facilitates user interaction is an important fea-
ture of this design. However, the customer has requested that the next generation product be substantially
smaller. This can best be achieved by eliminating the ASCII terminal.

The redesign promising the greatest size reduction integrates a large LCD panel and keyboard with an
M68HC11-based control unit. These changes meet customer requirements for a more compact, more tight-
ly integrated control solution, but as
Figure 2
indicates, the keyboard and LCD interfaces could exhaust the
digital I/O resources of the MC68HC711K4.
