20.4.5 External Trigger Input Timing
A/D conversion can be externally triggered. When the TRGE1 and TRGE0 bits are set to 1 in
ADCR, external trigger input is enabled at the ADTRG pin. A high-to-low transition at the
ADTRG pin sets the ADST bit to 1 in ADCSR, starting A/D conversion. Other operations,
regardless of the conversion mode, are the same as if the ADST bit had been set to 1 by software.
Figure 20.7 shows the timing.
