TINA/Spice/AM4378: VDDS3P3_IOLDO connection

Part Number:AM4378

Tool/software:TINA-TI or Spice Models

From the manual and other materials, the VDDS3P3_IOLDO pin should be connected to 3.3V, but I don't know why the reference schematic is grounded.

The official information below describes VDDS3P3_IOLDO connected to 3.3V
