Hi
It seems that the internal pull-down for pin# T3 is enabled by HW and it's not configurable by SW.
https://www.ti.com/lit/ds/symlink/omap-l137.pdf Table3-19:
User uses this signal as Input, and it is tied to 3.3V vie 10kΩ outside the device.
We don't know how much the internal resistance value for this pin is, and I'm afraid if this pin is floating with these internal pull-down and external 10kΩ pull-up.
Please advice how to confirm if it's ok or not.
Thanks and Best regards,
Tsurumoto.
