Notes:
1. Use when AV_CC = V_CC
2. Flash memory rewrite disabled. Except for the analog input pin, set the pins to be measured as input
ports and connect them to V_SS. See Figure 5.34 “A/D Accuracy Measure Circuit”.
3. When analog input voltage is over reference voltage, the result of A/D conversion is 3FFh.
