AD7865: Multiple CONVST

Question Is it possible to restart the con version with two consecutive /convst signals in direct requence (double function of signal necessary) ? The second pulse will follow the first directly (100ns pulse width ) Answer A conversion is triggered off the rising edge of convst, once started that is it until the selected conversion sequence is complete. Any further convst edges are ignored. So logically it will be ok to have a second convst directly after the first, but there is a risk of effecting the conversion accuracy if the pulse edges occur at critical times. Some notes we have indicate that the first critical position would be around 170ns after the first convst rising edge, but that is just a very rough guide. Have you considered gating out the second convst, possibly with the Busy signal? I have assumed the part is operating in internal clk mode, if the conversion is being clocked with an external clock then clocking after the second convst signal would be the thing to do.
