STM32L071 VREFINT_DIV

[Artur1]

Hello, my work mate made a design where we have to measure a low voltage in a smaller range (0-.120mV) on an Input.

His assumption and hardware realization to meet the requirements based on datasheet DS10690 Rev 6. Here on page 63 you can find the table which is saying about VREFINT divider 8see attached picture). But I'm a bit confused about it, I can't find a register where I can select the divider, no examples, no further information about it.

is there a divider available for STM32L071's vref_int or not? If yes, where can I find the register and the description.

VREFINT_DIV can be used as comparator reference

Hi Uwe,

agree I'v seen that the comparator threshold can be set to those levels, but the table is not about the comparator. The table is about the "internal reference voltage". And explicitly telling about VREFINT divider.
