AC Characteristics
the ADC input mode, the switching capacitor starts to charge up from 0 V. For the
maximum swing (Dout = 0 to FF), it takes 2/(0.0021x f ADC). For an 8-MHz MCU
crystal (with clock divide-by-two mode), the internal system clock is 4 MHz. In
ADCCTRL, if you select the ADC frequency = system clock divided by 1 option,
f ADC = 4 MHz. The step response = 238 uS.
Table 57 lists the AC characteristics.
