Inaccuracy in the article<p>&gt; The vast majority of digital logic works on only the rising edge of the clock. This means that transaction only happen when the clock toggles from 0 to 1, and nothing happens when going from 1 to 0.<p>Actually the majority of digital circuitry clocks data at the falling edge (0→1) transition. For example when programming SPI bus components it&#x27;s only the odd outlier that requires the clock polarity to be inversed.
