A/D conversion can also be started by an external trigger signal. Setting the TRGS1 and TRGS0
bits in DSADCSR to B'11 selects the signal on the ANDSTRG pin as an external trigger. The
ADST bit in DSADCSR is set to 1 on the falling edge of ANDSTRG, initiating A/D conversion.
Other operations are the same as those in the case where the ADST bit is set to 1 by software,
regardless of whether the converter is in single mode or scan mode. The timing of this operation is
shown in figure 19.10.
