Hi TI Experts,

Is there any application note with information about how to handle IOs or Peripherals - use or Unused

Details on the connections to be done when used.

When not used, should these IOs or Peripherals be left unconnected or connected to an pull-up or pull-down resistor.

Hi Board designers,

Handling of the Used IOs or Peripherals and Unused IOs or Peripherals depends on the family of processors.

The Following documents could be references

Device specific data sheet

Device specific Errata

Hardware Design Guide for family of devices

Schematic Design and Review Checklist for family of devices

These documents are available on the device specific product folder on TI.com. The product folder has many ore documents and tools that makes designing customer board simpler.

if you have any questions or not able to find the right collateral, reach out to TI support over E2E.

The assigned TI expert can point you to the required collaterals and also provide additional guidance.
