* If this API returns TAG_READ_REQUESTED, a full read is requested and the

* If this API returns TAG_WRITE_FULL, the nfc_tag_into_t has been filled
* with valid data pointers and sizes for both the static and dynamic parts
* to be written to the tag
* In the same fashion, if this API returns TAG_WRITE_DYNAMIC, a write for
* only the dynamic section of the tag is requested.
