The Keyboard and Mouse Interfaces (KMI) are implemented with two PrimeCells incorporated into the system controller FPGA. This is shown in Figure 3.24.
See also Keyboard and Mouse Interface, KMI and the ARM PrimeCell PS2 Keyboard Mouse Controller (PL050) Technical Reference Manual.
By default, the KMI connector will work directly with either a mouse or keyboard connected. The signals are connected to KMI0.
Plug a keyboard/mouse splitter into J7 to enable a mouse and keyboard to be used simultaneously.
