I'm transferring from AD7799 to AD7192 I already work with 7799 without any problem just I want more better low noise

my problem is that when I do setting for mode register then I read data , I got abnormal data( ffffff hex) but if I read without setting mode data is ok

my setting sequence like that

adc cs low

reset adc

power on switch

set config (ch1)

set mode ( cont conv) ****here is the problem

read ch1

note with 7799 i have no problem

what should I do to set mode register and start conversion
