Hi,

I'm using TRF7970A connected to the MSP430 MCU. The device I'm building works in two modes:

1. RFID tags reader. In this mode the device scans RFID tags and stores the data on an EEPROM. This works fine.
2. In this mode one device should read data previously stored on another device. For this I need the NFC function.

Despite the numerous timed I read the datasheet, I'm still confuse about the NFC function.

To allow one device reading data from another device, should I use a card emulator on one device only (the one that has the data) and no change to the reading device?
How do I configure such mode?
