Hello guys

When I need to enter the VLPS state and use the LPIT to generate the time base to scan in the VLPS state, but I don’t want to be awakened by the LPIT, what should I do?

Hello,

I'm not sure if I understand.

You can have the LPIT running in VLPS and disable the LPIT interrupt so that the MCU can stay in VLPS until it is waken up by another peripheral interrupt.

 

Regards,

Daniel
