It appears that the configurations for
ck_out_edge
were inverted forSPI_MODE2
andSPI_MODE3
. You can check the technical reference manual on page 76, table 23 "Clock Polarity and Phase, and Corresponding SPI Register Values for SPI Master".I've check with my oscilloscope that the current configuration is wrong and this fix corrects the issue.
Here are some examples writing

with theSCK
line in red and theMOSI
line in yellowSPI_MODE2
