Note 1: These parameters are not characterized or tested in manufacturing.
2: With no missing codes.
3: These parameters are characterized, but not tested in manufacturing.
4: Characterized with a 1 kHz sine wave.
5: The ADC module is functional at VBORMIN < VDD < 2.5V, but with degraded performance. Unless otherwise
stated, module functionality is tested, but not characterized.
