Trf7960a with mifare classic tag

[hthang1988]

Dear All,

I have a question about rfid function. I'm using TRF7960 reader chip to detect a mifare classic tag(1k). I've succeeded to configur the reader registers, configured it to ISO14443-A protocol. I was able to send REQA command and got the response from the tag, I sent SELECTS command and the tag responded in the anti-collsion program. Now the tag is selected but I don't know how to write or read data from the block memory of the tag, can anybody tell me please, how to write to some certain address in the tag or read from a certain address.

Thanks so much, please anyone with any small piece of information, reply and say it.

It is long time You wrote this post but anyway I will try to answer.
After select card according to the ISO14443-3 You need to perform authentication on this card describes for example in NXP document MF1S503x .
There You also have explained how to read and write data to some certain sector of Mifare Tag.
Hope to help somebody.
