Figure 83 shows the timing for ADC normal operation.
Figure 83. Timing for ADC Normal Operation
When the ADC is used so that the idle clock cycles occur between conversions (due to the negation of soc),
the selin inputs must be stable at least 1 clock cycle before the clock's rising edge where the soc signal is
latched. Also, selrefp and selrefn must be stable by the time the soc signal is latched. These conditions are
met if enadc=1 and reset=0 throughout ADC operation, including the idle cycles. If the conditions are not
met, or if power is lost during ADC operation, then a new start-up sequence is required for ADC to become
operational again.
