Notes:
1. Use when AV_CC = V_CC1 = V_CC2.
2. Do not use A/D converter when V_CC1 > V_CC2.
3. When analog input voltage is over reference voltage, the result of A/D conversion is 3FFh.
4. 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 5.3 “A/D Accuracy Measure Circuit”.
