TRF7970A: The B6 bit (lrq_srx) in the IRQ status register has not responded.

Part Number: TRF7970A

Hi team,

Here's the request from customer:

He puts the NFC tag on the TRF7970A module, using the driver source code officially provided, and found that only the B7 bit of the IRQ status register will be responded, and the other bits will not respond, resulting in the card search failure. 

Can you please check this case?

Thanks and Regards,

Nick
