WebOct 16, 2013 · 1. Clocks don't generally have an active "level" per say; in many cases clock outputs will specify that they'll only stop when they're at a certain level, but otherwise clocks have active edges. Typically, SPI devices will use one clock edge as a signal to output each bit of data, and the following clock edge as a signal that to latch the data ... WebPossible to disable SPI clock output?
