How it works
Logic is dual redundantly encoded so we can distingush data (DATAx) and no data (NULL). ... to be filled in.
How to test
You can't really test without a scope and a way to drive inputs

User feedback
- tommythorn👑: The single C-gate (driven by ui_in[1:0], outputting on uo_out[0]) works as expected, but the oscillator does not; it goes to a constant value when init = ui_in[2] is asserted. While it certainly oscillates much too fast for the output drivers, I had expected more randomness.
