Single Conversion Mode. In single conversion mode, a single conversion is performed
on the enabled ADC. Upon completion of a conversion, the ADC data registers
(ADC0H/M/L and/or ADC1H/M/L (ADuC845 only)) are updated. The relevant flags in
the ADCSTAT SFR are written, and power-down is re-entered with the MD2MD0
accordingly being written to 000.
Note that ADC0L is not available on the ADuC848.
