Hi Neeraj Gill-san,

The purple signal(DA4) is Digital input (4pin).
DA0 ->DA9 are same timing.

-Bus input : Dual-bus mode
-setup time ,hold time : 1nsec

Hi Itabi-san,

Looking at the figure that you sent me it looks like they are getting the Iout after 4 clk cycles which is as expected. Even if they are getting it after 5 clk I don't think this would be a problem.
