AD7656-1 number of reads

Hi,

 

we have implemented a design with AD7656-1 in parallel 16 mode, 6 channels. The conversion is started by CONVTS signal (A, B and C are connected parallel) and the resuts are read back by 6 RD pulses. The question is: what happens if i apply more than 6 RDs between two sampling periods? I have not found the descripton in the datasheet.

 

Does it read 0s or starts sending previously sampled values?

 

Regards, Peter
