AD9578 reset

Hi all,

I would like to better understand what the Master Reset bit does exactly, it load fabric presets?

Actually before start writing the configuration I enable the MR bit and then I toggle it, then I write my setup.

Sometime the setup is not working and I obtain a different frequency from what I expect, so I would like to know if the MR load the default value to all registers or not.

Moreover, if I change the register 5 (output divider) is possible that this change makes a Loss of lock of the PLL?
