ADSOI: ADC Stop-on-Interrupt bit
If ADCONT = 1:
1 = ADGO is cleared when the threshold conditions are met, otherwise the conversion is retriggered
0 = ADGO is not cleared by hardware, must be cleared by software to stop retriggers
If ADCONT = 0 bit is ignored.
ADTMD<2:0>: Threshold Interrupt Mode Select bits
111 = Always set ADTIF at end of calculation
110 = Set ADTIF if ADERR>ADUTH
101 = Set ADTIF if ADERRADUTH
100 = Set ADTIF if ADERRADLTH or ADERR>ADUTH
011 = Set ADTIF if ADERR>ADLTH and ADERR<ADUTH
010 = Set ADTIF if ADERR≥ADLTH
001 = Set ADTIF if ADERR<ADLTH
000 = ADTIF is disabled
