Hi,
I am an Hardware designer.
I need to know whether the VDDX and VDDA currents or voltages can be controlled through software.
I am using MCU S912ZVML64F1MKHR to one of my project.
Please let me know as soon as possible.
No, that is not possible.
These two rails must be connected together externally (at a board level).
Both voltages must be stable. The VDDA/VSSA supplies can be used as sources for VRH/VRL respectively and so stable voltage is important for ATD conversion accuracy.
