PN5180 Development board and Topaz 512 NFC Tags

I have PN5180 development board and NFC cockpit frontend software. I am able to read Mifare tags. I am not able to read data from Topaz 512 nfc tags. So, far this is what i am able to achieve

1. Place topaz 512 on the antenna

2. send REQA and able to receive ATQA 00 C0


I am not able to send any Topaz512 specific commands. I understand the protocol is different, Topaz512 requires every

byte needs sending in a separate frame.  I have tried few changes to some registers but no success.


I appreciate if somebody can provide me more details.
