15:35 <sb0> rjo, "no DDS accu clear, "relative phase offset mode"" << we can actually do that, if the gateware keeps tracks of the phase

15:35 <sb0> and I think the gateware has to keep track of the phase anyway

15:37 <sb0> I don't remember, can the ADI DDS take a IO_UPDATE pulse without phase discontinuities by default?

17:32 <rjo> sb0: context? we already do "no DDS accu clear"

17:36 <rjo> sb0: ... for sawg. for fast novogorny we would need to expose more than just ftw/pow/asf for the DDS and provide an API and mechanism to get that data accross.

18:27 <rjo> sb0: for the novogorny/urukul servo the gateware does not have to track the phase.
