4.2 I need to read a non-NFC compliant tag or transponder, what firmware example should I use?

If using MIFARE Classic® or MIFARE®DESFire® tags, see Section 4.4 for further details.

For all other proprietary RFID tags or transponders that have nonstandard activation or data exchange processes, TI does not supply example firmware. Therefore, custom firmware must be developed by the end user to handle such transponders on an application-specific basis.
