Hello,
ADS124S06 datasheet recommends to tie unused GPIO output pins to AVSS through a pulldown resister and set the output to 0.
ADS124S06’s default setting for GPIO pins is output. So I don’t think there is any risk to leave these pins floating because there are always output pins.
Why does the datasheet recommends to tie them to AVSS with pull-down? Is there any risk or concern?
Regards,
Oba
