The DE2 Board offers standard PS/2 interface with a connector for a PS/2 keyboard
or mouse. Figure 3.12 shows the schematic of the PS/2 connector and circuits. For
how to use PS/2 mouse and keyboards, users can refer to
http://www.computer-engineering.org for more information. The pin assignment of
the associated interface is shown in Table 3.10.
