Sample & Hold Time = (SHTIM+3) / ADCClock
Startup Time = (STARTUP+1) * 8 / ADCClock
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.
