HSE not enabled in stopmode for STM32L4 mcu.
port-stm32
I'm using a external HSE clock on the STM32L496 mcu. When I'm calling pyb.stop() the mcu won't return to the run mode. I've reported it here.
When I remove the "!" from the following line and then rebuilding it.

The code from the micropython forum does work. Is it a typo?

[NUCLEO-F091RC] MSE clock cannot be set
port-stm32
It seems that the STM32F091RC uses the internal MSI on 48MHz. Hooking up an external crystal does not help :-) it seems there no support yet in setting the HSE clock options of the STM32F0xx.
It would be nice to have this flexibility as with all other boards supported :-)
