low power oscillator is used for 12-bit mode. The values in the table assume that the oscillators run at their
nominal frequencies. The maximum SAR clock values given in Table 4.10 allow for maximum oscillation
frequencies of 25.0 MHz and 22 MHz for the precision and low-power oscillators, respectively, when using
the given SAR clock divider values. Energy calculations are for the ADC subsystem only and do not include
CPU current. 12-bit mode is only available on
