If the ADCON0 register is rew ritten during A/D conversion, the conversion result is undefined.
Bits CH0 to CH2 are enabled w hen the ADGSEL0 bit is set to 1.
After changing the A/D operating mode, select the analog input pin again.
Set øAD frequency to 10 MHz or below .
If the ADCON1 register is rew ritten during A/D conversion, the conversion result is undefined.
Set the BITS bit to 0 (8-bit mode) in repeat mode.
