Number of ADC clock cycles to wait for: (STARTUP + 1) * 32.
1: The multiplexers settle time is set to 0.5 PB clock periods.
0: The multiplexers settle time is set to 1.5 PB clock periods.
1: The external forcing of references is enabled, ADC references are the ADCREFN and ADCREFP pads.
0: The external forcing of references is disabled, ADC reference is given by the RS field.
1: The Sample and Hold is disabled.
0: The Sample and Hold is enabled.
note: when set to one, sequencer 1 is turned off, as a consequence the ADC pipeline latency is decreased by one ADC clock
period.
0: Internal 1V reference.
1: Internal 0.6 *VDDANA reference.
2: External reference ADCREF0 over chip analog ground.
3: External reference ADCREF1 over chip analog ground.
1: The free running mode is enabled, sequencer 0 performs conversions continuously.
0: The free running modeis disabled.
note: once in this mode, sequencer 1 requests cannot be serviced.
