WebSPI has 4 different modes: These modes refer to how data is sampled with the clock pulses. A clock polarity (CPOL) of 0 means that the clock line idles low whereas a CPOL of 1 means the clock line idles high. If clock phase (CPHA) is 0, bits are sampled on the leading clock edge and if CPHA is 1, bits are sampled on the trailing clock edge. electric trailer brakes tester
