13.3.2.6
Writes to this register will abort current conversion sequence and start a new conversion sequence. If
external trigger 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.

Sample Time Select — These three bits select the length of the sample time in units of ATD conversion clock
cycles. Note that the ATD conversion clock period is itself a function of the prescaler value (bits PRS4-0).
Table 13-14
ATD Clock Prescaler — These 5 bits are the binary prescaler value PRS. The ATD conversion clock frequency
is calculated as follows:
