In one-shot conversion mode, the ADCS bit is automatically cleared to 0 after completion of A/D conversion. 
In sequential conversion mode, A/D conversion operations proceed continuously until the software clears bit 7 (ADCS) 

of the A/D converter mode register 0 (ADM0) to 0. 

Writing to the analog input channel specification register (ADS) during A/D conversion interrupts the current conversion 

after which A/D conversion of the analog input specified by the ADS register proceeds. Data from the A/D conversion that 
was in progress are discarded. 

Reset signal generation clears the A/D conversion result register (ADCR, ADCRH) to 0000H or 00H.
