Start of conversion or trigger generation. Software controlled start of conversion
if SD24SCS = 00b. Manual stop of conversion (independent of SD24SCS
setting).
If a conversion is ongoing (triggered by any source selected through SD24SCS)
this is indicated by SD24SC = 1.
0b = No conversion start or stop conversion
1b = Start conversion or trigger generation
