Trailing leading spi
Splet02. feb. 2012 · CPHA indicates the clock phase used to sample data; CPHA=0 says sample on the leading edge, CPHA=1 means the trailing edge. Since the signal needs to stabilize before it’s sampled, CPHA=0 implies that its data is written half a clock before the first clock edge. The chipselect may have made it become available.
