As far as I can tell, the AVR numbers for dataMode appear to match the numbers required by the STM32

SPI Mode CPOL CPHA Shift SCK-edge Capture SCK-edge
0 0 0 Falling Rising
1 0 1 Rising Falling
2 1 0 Rising Falling
3 1 1 Falling Rising
On the STM32 it appears to be
bit 1 - CPOL : Clock polarity
(This bit should not be changed when communication is ongoing)
0 : CLK to 0 when idle
1 : CLK to 1 when idle
bit 0 - CPHA : Clock phase
(This bit should not be changed when communication is ongoing)
0 : The first clock transition is the first data capture edge
1 : The second clock transition is the first data capture edge
If someone finds this is not the case or sees a logic error with this let me know ;-)
