Notes:

1. Vcc/AVcc = 1.8 V to 5.5 V and Vss = 0 V and Topr = -20

°C to 85 °C (N version)/-40 °C to 85 °C (D version), unless otherwise

specified.

2. The A/D conversion result will be undefined in stop mode, or when the flash memory is in low-current-consumption read mode

or stopped. Do not perform A/D conversion in these states. Do not enter these states during A/D conversion.

Notes:

1. Vcc = 2.7 V to 5.5 V and Topr = -20

°C to 85 °C (N version)/-40 °C to 85 °C (D version), unless otherwise specified.

2. When the digital filter is disabled.
