Pad keeping is not taking effect？

PINKMAN — Wed, 04 Jun 2025 13:53:19 GMT

hello expert:

In my project, there is a wakeup source which is falling edge trigger. but i can read it from IP_WKPU->WISR even it doesn't happened.

before go to standby mode , i already enable Pad_Keeping by

IP_DCM_GPR->DCMRWF1 &= ~DCM_GPR_DCMRWF1_STANDBY_IO_CONFIG_MASK;

after wakeup ,i disable it by

IP_DCM_GPR->DCMRWF1 |= DCM_GPR_DCMRWF1_STANDBY_IO_CONFIG_MASK;

i think it should not happend in IP_WKPU->WISR

can you tell me why ?

I can see this is the same question as in this community post: WKPU->WISR and Pad_Keeping question - NXP Community.

I've replied to you there, is it okay to close this thread and keep support through the other one?

Best regards,
Julián
