TMS320F280039C: SDFM shift value

Hi Champ, 

I want to check the shift value when I use SDFM from 26bit to 16 bit format. As shown below, 2097125 = 2^21, 32768=2^15. So I understand we need shift 6 bit to complete the conversion. Why we configure shift control
bits (SDDPARMx.SH) to 7? 

BR,

Fengyu
