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)
