Datasheet only describe it as referece to functional timing diagrams in SPI chapter, but there isn't in datasheet for both DA14580 and DA14583 ?
在哪里?
是的,届is part is omitted in the datasheet.SPI_POL: 0// when in idle mode, clock =0;1//when in idle mode, clock =1
if SPI_POL ==0, then leading edge is 0->1, tail edge is 1->0if SPI_POL ==1, then leading edge is 1->0, tail edge is 0->1
SPI_PHA: 0 //leading edge sample the data1//tail edge sample the data
check the attachment for detail timings
