Disable NFC Interrupt

Question

Hi, 
 The NFC function is set to read only in my application. I don't want to wake up my system when someone tap on my device to read the NFC data. (assume this method can save more power) 
 Should I just disable NFC interrupt? If yes, please tell me how to do it; if not, please kindly give me any suggestion. 
 Thanks.

Not really. If you want to use NFC HW peripheral block (e.g. it you expect to be working with reader once antenna enters the field) then no you cannot disable interrupt. If you are optimizing power consumption, there is essential Q&A from Stefan . It's for nRF51 but it's very much applicable for nRF52 as well. There is nothing about NFC but that's only small part, like cherry on top of the cake. If you want to use it, you need to have it active, otherwise disable it. Simple as that.
