1.1.1.3. Switch Matrix

The switch matrix has input, output, and multiplexer select pins. You can connect all 16 inputs to the multiplexer of each output, allowing you to independently connect any output to any input and any input to any or all outputs.

You can always add features to the output cell. For example, you can add another tri-state buffer or register at the output of the multiplexer.
