High sleep current after switching oscillator source from MSI to HSI and back to MSI.

DJack.8 · ‎2021-12-23

Once I switch to the HSI clock source and switch back to MSI my sleep current increases from 25uA to 500uA. Maybe HSI is turning something on that the MSI configuration is not turning off. I can't find it. Any help is greatly appreciated.

Check if it turns off HSI and PLL after the switch to MSI.
