Notes:

1. VCC/AVCC = Vref = 2.2 to 5.5 V, VSS = 0 V at Topr = 20 to 85 C (N version) / 40 to 85 C (D version), unless otherwise

specified.

2. The A/D conversion result will be undefined in wait mode, stop mode, when the flash memory stops, and in low-current-

consumption mode. Do not perform A/D conversion in these states or transition to these states during A/D conversion.

3. 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.

Notes:

1. VCC = 2.7 to 5.5 V, Topr = 20 to 85 C (N version) / 40 to 85 C (D version), unless otherwise specified.

2. When the digital filter is disabled.
