I have been working with KM14Z microcontroller to read the voltage and current through SAR ADC and the AFE module.

I am using the internal Vref as reference. The voltage i am getting in Vref is 0.26V, Vrefl is 0.1V and Vrefh is 0.28V.

Vref init module,

/* Vref Init */





Actual Vref should be around 1.2V. Please help me understand the problem with the code


Thanks in Advance.
