for STM32F405RGT, for the ground pin of HSE crystal oscillator 's load capacitor ,should it connect to the AGND or DGND? Because I use the ADC of the MCU,so i seperate the AGND(vssa) and DGND(vss).
I want the ADC of the MCU be more accurate.I know the PLL belong to the power field of the VDDA .Thanks.
