Description
ATD Sequence Complete Interrupt Enable
0 ATD Sequence Complete interrupt requests are disabled.
1 ATD Sequence Complete interrupt will be requested whenever SCF=1 is set.
ATD Compare Interrupt Enable — If automatic compare is enabled for conversion n (CMPE[n]=1 in ATDCMPE
register) this bit enables the compare interrupt. If the CCF[n] flag is set (showing a successful compare for
conversion n), the compare interrupt is triggered.
0 ATD Compare interrupt requests are disabled.
1 For the conversions in a sequence for which automatic compare is enabled (CMPE[n]=1), ATD Compare
Interrupt will be requested whenever any of the respective CCF flags is set.
