A/D conversion can also be started by an external trigger input. When the TRGE bit in ADCR is
set to 1, external trigger input is enabled at the ADTRG pin. A falling edge at the ADTRG input
pin sets the ADST bit in ADCSR to 1, starting A/D conversion. Other operations, in both single
and scan modes, are the same as when the bit ADST has been set to 1 by software. Figure 18.3
shows the timing.
