Hello,friends.Now i'm using  TC277 chip with BGA292, and now there are some unused pins on the hardware schematic.

Now I need to configure these pins using EB  tresos.But I couldn't find a recommended configuration status for these unused pins in the chip manual.  

Could you tell me where I should go to look for it? The unconnected ports are mainly port pins and adc pins.

Hi @kangsenliu ,
To provide the fastest support, I'd highly recommend you refer to the Recommendation for unused pins section on Page 4 in the PCB Design Guidelines application note AP32174.

 Hey,friend.Sincerely appreciate your reply!

I have already find the I/O port pins solution,but i am also  troubled by the adc pins, such as analog input pins like U9pin   AN3/VADCG0.3/DS0NA ,can I just leave the pin out?
