Hi,
I'm trying to wake up the KL46 processor from vlls3 mode using RTC alarm. But it is not waking. Even RTC seconds interrupt is not able to wake up the processor from VLLS3 mode only pin interrupt is working.
Can anyone help me.
Best Regards,
Shabana
Hi Shabana-san,
I guess the RTC was not clocked in the power mode. By default, RTC is clocked by OSC32KCLK which would be stopped in the power mode. I think you had better change the setting of SIM_SOPT1[OSC32KSEL] from OSC32KCLK to LPO.
Best regards,
Yasuhiko Koumoto.
Hi Shabana,
I was wondering if you can upload your demo to the community, then I can run the demo with FRDM-KL46Z board.
I'm looking forward to your reply.
Have a great day,
