Hello, i'm using RX111 (R5F51115ADFM) controller in our project, wherein one of the requirement is to read out Voltages at four different locations in the circuit. So i make use of the inbuilt ADC module to do the same, and have been successful in producing 25 such units of the project. But, in one of my board, the ADC Module somehow doesn't seem to work. It always gives an output ZERO though there is voltage at the ADC pin as well as at the AVCC pin. Every other functionality seems to be perfectly functioning. Can anyone help me out in finding what might be the possible reason for the ADC module malfunctioning. Is it a Faulty IC or have i missed out on something?
