Is it possible to measure the internal VDD wihtout adding any external hardware?
It would be nice to see VDD voltage before doing an IFU, due the risk of going under DRAM minimum vdd supply wich is 3.0V.
Hmm, I don’t see how to do that without using a voltage divider on an analog input pin.
problem might be that the reference voltage of the AD converter is also derived from VCC
Which SOM?
