Hello,
One of my customers is testing TLV320ADC5140. they success to operate TLV320ADC5140 unless DRE function. Do you mind helping to have a view on below code? I thought it's cause by unwriting 6C register. Do you mind helping to check are there some other issue to cause DRE unwork?
Many thanks for your help!
