We offer this simple PS/2 controller coded in Verilog HDL to demonstrate bidirectional
communication between PS/2 controller and the device, the PS/2 mouse. You can treat it as a
how-to basis and develop your own controller that could accomplish more sophisticated instructions,
like setting the sampling rate or resolution, which need to transfer two data bytes.
For detailed information about the PS/2 protocol, please perform an appropriate search on various
educational web sites. Here we give a brief introduction:
 Outline
PS/2 protocol use two wires for bidirectional communication, one clock line and one data line. The
PS/2 controller always has total control over the transmission line, but the PS/2 device generates
clock signal during data transmission.
