I sometimes do not get repeatable spur behavior on the eval board while switching through a sequence of different settings for the FRAC_ORDER, FRAC_DITHER, FRAC_NUM, and FRAC_DEN.
When I return to my initial settings, the spur behavior is sometimes not identical to the initial state.
I suspect that the seed value is not the same anymore, but I can't find how to change the seed value in the datasheet.
Is there a way to reset or set the mash seed? Is the only way to reset the seed is to do a software reset on register 2?
