[MQX]: K20 low power mode with UART on?

[huishao2]

Hi-

I need to find MQX application notes for power saving on a K20D50M based board. The board needs to stay in low power mode while leaving UART on. Wondering if there is such application notes to help? The system is MQX3.8 powered.

Thanks!

Hi Sol

Thanks for your reply!

Wondering if there is a more specific app notes with demo code to assist on my application. A k20d50m custom board running MQX4.1. I am trying to make it into low power either with UART active or wake it up by RxD transition.

Regards

Hui
