Table 27.19 lists the A/D converter characteristics.
Table 27.19 A/D Converter Characteristics
Conditions: Vcc = PLLVcc = 1.4 V to 1.6 V, VccQ = 3.0 V to 3.6 V,
AVcc = AV_ref = 4.5 V to 5.5 V,
Vss = PLLVss = VssQ = AVss = AVREFVss = 0 V, Ta = −40°C to +85°C,
V_AN0-2 = 0.25 to AVcc −0.25 V, V_AN3-7 = 0 V to AVcc

Notes: 1. The values in parentheses are reference values.
2. Conversion time per channel during continuous conversion. For the time from
continuous conversion start to end, refer to section 17, A/D Converter (ADC).
3. The conversion error between 0 to 0.25 V of the AN0 to AN2 inputs and AVcc -0.25 V to
AVcc does not meet the above value.
