WebSep 15, 2024 · if the clock is low and the data is read by the receiver on the leading rising edge, that means that the receiver reads a bit before the transmitter sends anything. … WebThe clock phase determines the phase at which the data latching occurs at each bit transfer whether it’s the leading edge or the trailing edge. The clock polarity determines the IDLE state of the clock line whether it’s a HIGH or LOW. Having 2 possible states for each of the CPOL and CPHA gives us a total of 4 possible modes for the SPI clock.
