AD9x89B_Initial_Preset_values

Question asked by mra on Oct 4, 2011

There is a zip folder in "AD9889B/AD9389B Design Support Files" (http://ez.analog.com/docs/DOC-1741) with a few configuration scripts for AD9889B/AD9389B. When I compare the scripts I find some differences, but most of them are related to "read-only", "do not write" and "Fixed" registers.

 

Is there any actual difference between the scripts?
