NOTES:
1.
VCC = AVCC = 2.7 to 5.5 V at Topr = -20 to 85
°C / -40 to 85 °C, unless otherwise specified.
2.
If f1 exceeds 10 MHz, divide f1 and ensure the A/D operating clock frequency (
φAD) is 10 MHz or below.
3.
If AVcc is less than 4.2 V, divide f1 and ensure the A/D operating clock frequency (
φAD) is f1/2 or below.
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.
