1. If the ADCON0 register is rewritten during A/D conversion, the conversion result will be undefined.
1. If the ADCON1 register is rewritten during A/D conversion, the conversion result will be undefined.
2. AN0_0 to AN0_7, and AN2_0 to AN2_7 can be used in same way as AN0 to AN7. Use bits ADGSEL1 to
3. If the VCUT bit is reset from 0 (VREF unconnected) to 1 (VREF connected), wait for 1 µs or more before
