Wakeup PN7462 on falling edge of GPIO interrupt

Hi,

In our custom board, we are using PN7462 IC. We are putting PN7462 into standby mode. We want to wake up on the falling edge of GPIO interrupt. We have tried with the below example code.

After further debugging we come across section 8.3.4 Wake-up from Standby/Suspend Mode in the datasheet we found PN7462 wakes up on GPIO transition 0 to 1 (Rising edge). How to wake up on GPIO transition 1 to 0 (Falling edge) as our costume board required to use falling edge?

Hello @bhavind ,

 

I have checked with the expert team, and it seems that GPIO wakeup only supports 0 to 1.

 

Sorry for the inconvenience that has caused.

 

Have a great day,
Kan
