In STM32CubeMX clock schematic and in the clock schematic of the reference manual CK_PWR is mentioned. It is never explained what it does and what it is for.I'd like to know what it is for and how it affects current consumption (since it is before th...

I supply my STM32G4 with 3.3V. The 3.3V is more like 3.246 Volt. The VREF+ is connected externally to VDDA, which is connected to the 3.246V.My VREFINT_CAL_ADDR is 1662. On the Vref channel of the ADC I measure 1465, so I calculated 3.4034V for VDDA....

I select tim1 for sys source in STM32CubeMX and generate code.I use STM32CubeMX V6.4.0.I added a stripped example of the code that crashes. HAL_NVIC_EnableIRQ crashes.
