RTC and LLWU problem.

albertmartin — Mon, 13 Apr 2015 14:18:17 GMT

good morning:

I'm doing a test of RTC and LLWU.

I set LLWU_ME_WUME7 bit, and i have also enabled the RTC and interrupt to 1 second.

I go to Deep Sleep, and when I wake up, I have activated the RCM_SRS0_WAKEUP_MASK flag but none more.

the LLWU_F1_WUF7 and LLWU_F1_WUF5 flag are not enabled.

I implemented it on MK60FN1M0VMD12 by Keil environment.

Thank you very much.

Hello Albert,

you should check LLWU_F3 instead of LLWU_F1.

By the way, as the simple Deep Sleep mode is the STOP mode, the wakeup will be made by AWIC.

If you used a simple STOP mode, you should use NVIC and set properly NVIC.

The wakeup by LLWU is applicable for LLS or VLLSx.

Best regards,
