Hello

 

Could you give me your advice about below opeartion of AD7192 ?

 

1

Datasheet P13 says below about Pin 13 DOUT/ RDY .

 

"If the data is not read after the conversion, the pin goes high before the next
update occurs."

 

Does above mean that  RDY output   toggles (Low - High-  Low )  before next update occurs

when we do not read the data register ?

 

2

Datasheet P31 says below.

 

"the user must ensure that the data register is not being accessed at
the completion of the next conversion or else the new conversion word is lost."

 

Can we read the old data correctively  even if  the new conversion word is lost  when data register is not being accessed at the completion  ?

If the  register access at the completion timing  is not recommended, please let me know it.

 

Regards,

Terumasa
