22   reference-buffer:
24       Enable precharge buffer, full buffer, or skip reference buffering of
25       the positive/negative voltage reference. Because the output impedance
26       of the source driving the voltage reference inputs may be dynamic,
28       errors if the reference inputs go unbuffered into the ADC. Enable
29       reference buffering if the provided reference source has dynamic high
31       inputs is from AVSS - 50 mV to AVDD + 50 mV when the reference buffers are
32       disabled but narrows to AVSS to AVDD when reference buffering is enabled
47       Reference voltage supply for AVSS. A −2.625V minimum and 0V maximum supply
