Using MFRC522 to wake up AtMega328?

Dear all,

I have a MFRC522 which connects directly to my chip AtMega328. It consumes lots of energy. The problem is when I put AtMega328 to sleep, I can't use the MFRC522. Is there any way using MFRC522 to wake up the ArMega chip?

Does the MFRC522 have a pin that goes HIGH when it detects a card to read? If so you could use that to trigger an external interrupt to wake up the ATmega.
