Notes:
1. Use when AV_CC = V_CC1.
2. When V_CC1 ≥ V_CC2, set as below:
Analog input voltage (AN0 to AN7, ANEX0, and ANEX1) ≤ V_CC1
Analog input voltage (AN0_0 to AN0_7 and AN2_0 to AN2_7) ≤ 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 5.2 “A/D Accuracy Measure Circuit”.
