AD7366 ~BUSY state at power up

Hi,

   My question is related to the power-up state of the BUSY signal of the AD7366 ADC converter.

   According to the data sheet this signal remains low until a conversion is initiated. In my design, I notice that often after powering up my board, the BUSY signal is in logic high level and I cannot perform any conversion as there is no response from the BUSY signal. I tried shutting down and then powering on the AD7366 by using the CNVST signal as documented in the datasheet, to no avail.

   My question is: which are the conditions that may cause the BUSY signal to show in logic level high after powering up the board?

 

Thank you in advance,

Cosmin.
