How to generate Hardware interrupt to wake MCU from deep power down when the card is detected?

[mahendrasondaga]

Hello freaks,

I'm dealing with the battery  operated NFC based application and i need to conserve the battery as much as i can.

For the card R/W and P2P mode I'm using PN7150. I know about it's Low power card detection mode (LPCD) to significantly reduced power consumption but i also need to put my Host processor in Deep power down and need to wake-up when the card enters in filed (just like NT3H1101 FD pin and PN532 P70_IRQ)  can any one guide me here

Thanks
