2. If f1 exceeds 10 MHz, divide f1 and ensure the A/D operating clock frequency (φ
3. If AVcc is less than 4.2 V, divide f1 and ensure the A/D operating clock frequency (φ
4. When the analog input voltage is over the reference voltage, the A/D conversion result will be 3FFh in 10-bit mode and FFh in
8-bit mode.
