16.3.2.6
Writes to this register will abort current conversion sequence and start a new conversion sequence. If the
external trigger function is enabled (ETRIGE=1) an initial write to ATDCTL5 is required to allow starting
of a conversion sequence which will then occur on each trigger event. Start of conversion means the
beginning of the sampling phase.

Special Channel Conversion Bit — If this bit is set, then special channel conversion can be selected using CD,
CC, CB and CA of ATDCTL5.
0 Special channel conversions disabled
1 Special channel conversions enabled
Continuous Conversion Sequence Mode — This bit selects whether conversion sequences are performed
continuously or only once. If the external trigger function is enabled (ETRIGE=1) setting this bit has no effect,
thus the external trigger always starts a single conversion sequence.
0 Single conversion sequence
1 Continuous conversion sequences (scan mode)
