Where is the description of SPI_PHA settings ?

Datasheet only describe it as referece to functional timing diagrams in SPI chapter, but there isn't in datasheet for both DA14580 and DA14583 ?

是的,届is part is omitted in

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->0
if SPI_POL ==1, then leading edge is 1->0, tail edge is 0->1

SPI_PHA: 0 //leading edge sample the data
1//tail edge sample the data

check the attachment for detail timings
