ATD Fast Flag Clear All
0 ATD flag clearing done by write 1 to respective CCF[n] flag.
1 Changes all ATD conversion complete flags to a fast clear sequence.
Do not alter this bit from its reset value.It is for Manufacturer use only and can change the ATD behavior.
External Trigger Level/Edge Control — This bit controls the sensitivity of the external trigger signal. See
Table 12-7
External Trigger Polarity — This bit controls the polarity of the external trigger signal. See
External Trigger Mode Enable — This bit enables the external trigger on one of the AD channels or one of the
ETRIG3-0 inputs as described in
input buffer of this channel is enabled. The external trigger allows to synchronize the start of conversion with
external events.
0 Disable external trigger
1 Enable external trigger
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), an ATD Compare
For compare disabled (CMPE[n]=0) a read access to the result register will cause the associated CCF[n] flag
to clear automatically.
For compare enabled (CMPE[n]=1) a write access to the result register will cause the associated CCF[n] flag
to clear automatically.
Interrupt will be requested whenever any of the respective CCF flags is set.
