S32K3xx: Wakeup by EIRQ pins?

tecprasant

Hi,

In my custom S32K3 hardware I have external GPIO interrupt on a EIRn supported pin? Can I use EIRQ interrupt to wake up the controller when the controller is in sleep / standby mode ? (Note: This EIRQn does not have any WKPU option).

Would it be possible to wake up if the EIRQn pin had WKPU option also?

Any inputs on this would be of help.

Regards,

Robin_Shen

Hi

Please read the chapter 48.1.4 WKPU wake-up source connectivity of S32K3XXRM Rev8. EIRQn is not listed, but if the EIRQn pin you choose also has WKPU[0]-WKPU[59] function, it can be configured as WKPU before entering standby.

Best Regards,
Robin
