If the ADCON0 register is rew ritten during A/D conversion, the conversion result is undefined.
After changing the A/D operating mode, select the analog input pin again.
Set øAD frequency to 10 MHz or below .
The analog input pin can be selected according to a combination of bits CH0 to CH2 and the ADGSEL0 bit.
