Hello,
There ares several inconsistencies in the Technical Reference Manual / Spruj17 / March 2022 in terms of the ADC reference system.
6.1.1.1.2.1 ADC Reference Buffer Control Registers
....The voltage rails ADC_VREF*_G2 connects to REFBUF1, ADC3, and ADC4
vs
Figure 6-2
ADC_VREF*_G1 connects to REFBUF1, ADC3, and ADC4
I assume the text is correct and the figure is wrong.
Figure 7-91. ADC reference system is missing.
Could you please update the chapter about ADC reference system?
Most likely figure 7-91 could clarify most questions.
br,
Bernhard
