TRF7970A: Some issue about designing pear to pear mode.

Part Number: TRF7970A

Hi team,

Here's the request from the customer:

At present, customers have completed the reading and writing of TRF7970A registers and the function of sending instructions. Now they have two boards, and they want one board to send and the other board to receive, so as to realize the P2P function. They read the NFC active and passive peer to peer communication using the TRF7970A on the official website. They are not very clear about how to configure the registers for the initialization of the two boards, and the corresponding process. They wonder if there are any special P2P development program cases that can be used as a reference?

Could you help check this case? Thanks.

Best Regards,                                                        

Nick
