My name is Ruslan, I am a Technical Project Manager at Aduk GmbH.
We bought from you the NHS3100TEMOADK: NHS3100 Starter Kit for Temperature Monitoring and cannot find the referens manual with register descriptions for the NHS3100, in particular the NFC HW block.
You can download the HW User Manual from e.g. https://www.nxp.com/pages/:NHS3100 > DOCUMENTATION > Users Guide: UM10876. It is also available in the SDK under <SDK>/docs/UM10876.pdf. The SDK can be downloaded from https://www.nxp.com/pages/:NHS3100 > TOOLS & SOFWTARE > Embedded Software: NHS3100 SDK.
The register description is listed under chapter 11 RFID/NFC communication unit paragraph 7 Register descriptions
