Wakeup signal

Hello,

I am trying to configure a wakeup signal WKPU6 as below.

WKUP.WISR.B.EIF = 0x02000000; //Clear interrupt flag

WKUP.WIREER.B.IREE = 0x02000000; //Disable rising edge

WKUP.WIFEER.B.IFEE = 0x02000000; //Enable falling edge

WKUP.IRER.B.EIRE = 0x00000000; //Enable interrupt

WKUP.WRER.B.WRE = 0x02000000; //Enable system wakeup

WKUP.WIFER.B.IFE = 0x02000000;

But when above code is executed, after the first statement, the code looses the track and never returns. What is the reason? I have tried to configure the bits from another end as well. Can you please clarify the behavior? Any test app for wakeup up signal?

Thanks in advance for all your help.

Mike.

Hello Mike ,

You have forgotten to configure the WKPU PCTL it should be enabled in STOP0 Mode

halSPCSetPeripheralClockMode(69,
SPC5_ME_PCTL_RUN(2) | SPC5_ME_PCTL_LP(3));

Best Regards Erwan
