12-bit ADC characteristics

Unless otherwise specified, the parameters given in Table 82, Table 83 and Table 84 are

derived from tests performed under the ambient temperature and VDDA supply voltage

conditions summarized in Table 12: General operating conditions. In Table 82, Table 83 and

Table 84, fADC refers to fadc_ker_ck.
