Sample & Hold Time = (SHTIM+3) / ADCClock
Startup Time = (STARTUP+1) * 8 / ADCClock
This Time should respect a minimal value. Refer to Electrical Characteristics section for details.
ADCClock = CLK_ADC / ( (PRESCAL+1) * 2 )
1: Sleep Mode is selected.
0: Normal Mode is selected.
1: 8-bit resolution is selected.
0: 10-bit resolution is selected.
1: The hardware trigger selected by the TRGSEL field is enabled.
0: The hardware triggers are disabled. Starting a conversion is only possible by software.
