AD7768 - Conversion Data Output (DOUT6/7)

I have configured my AD7768 such that all conversion data will get output on DOUT0 (i.e. connect my FORMATx pins to logic 1).

I understood from the datasheet that, if daisy-chaining feature is not intended to be used, DOUT6 and DOUT7 will then need to be connected to DGND through a pull-down resistor.  I was hoping to find out what resistor values do you guys recommend as this was not mentioned in datasheet.  Or is it not necessary to use resistors?


Thank you in advance for the help in clarifying!
