I have a question with regards pin that are not used in 2156x .
1.When are not using Vdd_ana is fine to keep it NC or we need to connect to a power source .
2.If there are unused PA , PB or PC can they be left NC or should it be connected to ground .
With regards previous sharc DAI pin can be used as GPIO , can we use DAI as GPIO , If we can can you share us a sample code as to how to do it .
With best regards
