Proper way to send 16 bit SPI data

I need to send 8 bit and 16 bit data with my 32f769. I found a register modification routine to change the bits from 8 to 16 and back. I checked the SFRs and it works (changing the bits that is),When I transmit 8 bit data, all is fine. I can send ...

Resolved! Is there a better way to generate a variable frequency using DMA and TIM2 than what is described in AN2820 Paragraph 2.2.1 Page 13/14?
