Notes: 1. Set AV_CC = V_CC when the A/D converter is not used.
2. AI_STOP1 is the current in active and sleep modes while the A/D converter is idle.
3. AI_STOP2 is the current at reset and in standby, watch, subactive, and subsleep modes
while the A/D converter is idle.
4. When internal power supply step-down circuit is not used.
5. Conversion time: 124 µs
