    Changing Channel or Reference Selection
    The MUXn and REFS1:0 bits in the ADMUX Register are single buffered through a temporary
    register to which the CPU has random access. This ensures that the channels and reference
    selection only takes place at a safe point during the conversion. The channel and reference
    selection is continuously updated until a conversion is started. Once the conversion starts, the
    channel and reference selection is locked to ensure a sufficient sampling time for the ADC. Con-
    tinuous updating resumes in the last ADC clock cycle before the conversion completes (ADIF in
    ADCSRA is set). Note that the conversion starts on the following rising ADC clock edge after
    ADSC is written. The user is thus advised not to write new channel or reference selection values
    to ADMUX until one ADC clock cycle after ADSC is written.
    If Auto Triggering is used, the exact time of the triggering event can be indeterministic. Special
    care must be taken when updating the ADMUX Register, in order to control which conversion
    will be affected by the new settings.
    If both ADATE and ADEN is written to one, an interrupt event can occur at any time. If the
    ADMUX Register is changed in this period, the user cannot tell if the next conversion is based
    on the old or the new settings. ADMUX can be safely updated in the following ways:
    1.
    When ADATE or ADEN is cleared.
    2.
    During conversion, minimum one ADC clock cycle after the trigger event.
    3.
    After a conversion, before the Interrupt Flag used as trigger source is cleared.
    When updating ADMUX in one of these conditions, the new settings will affect the next ADC
    conversion.
