Good day,


I'm a engineer using PN7462AU. I am developing an NFC communication program. 

My question is very similar to this question. But there's no answer on that page.

※ URL : PN7462 GPIO Interrupts 


I want to use GPIO as an interrupt source. When I receive the GPIO signal, I want to call the callback function.

There are API about GPIO. But I can't find API about setting GPIO callback function.


Question 1) Is there an API to set GPIO callback function?

 - For example, using GPIO1, how to setting dwPcrIRQMessage?

 - Should I use phhalPcr_RegCallBack ()?

Question 2) How to use GPIO as an interrupt source?



Below is the setup details,

1. Hardware: PN7462AU
2. SDK: PN7462AU-FW_v05.21.00
3. IDE: MCUXpresso IDE v11.0.0
