Using the NFC example provided in the RF430FRL152H firmware, you can use user-defined NDEF messages that will be recognized by NFC handsets. Some older NFC mobile handsets do not support NFC Tag Type 5 configured tags but still support ISO/IEC 15693 RFID with raw transceiver commands, like read and write single block.
When NDEF support is used, much of the ROM functionality must be deactivated, because the NDEF message and the virtual registers share the same portion of memory. Only the RF stack is supported with this feature. While the ROM in this mode cannot take SD14 measurements and there is no host controller support, the SD14 and I2C or SPI modules are still functional and can be controlled by custom user code in FRAM. For the example projects provided (see Section 2.4 ) only the NFC example has NDEF support. The "Default" and "SensorHub" examples only have ISO/IEC 15693 RFID support.
NOTE
The term virtual registers refers to all the registers that exist in FRAM memory space that are programmable over RF (or a host controller) and control ROM operation.
