The parameter 

mode16

 determines the data length mode, which can be 8-bits (per transmitions cycle) 

or 16-bits. 

The parameter 

sec_prescaler

 determines the value of the 

secondary SPI clock prescaler. Used 

only in the Master Mode. 

The parameter 

pri_prescaler

 determines the value of the 

primary SPI clock prescaler. Used only 

in the Master Mode.
