ADAU1372 unused analogue pins

Page 28 of the ADAU1372 data sheet under the heading Analog Inputs states "Connect unused input pins to the
CM pin or ac-couple them to ground."


Under the heading Analog Line Inputs its states when single ended "Tie the AINxREF pins to the CM pin."


The data sheet for the EVALADAU1372 page 14 shows unused AIN2REF and AIN3REF pins AC coupled to ground.


Which is the correct connection for unused AINxREF pins?
