14.4.4 External Trigger Input Timing
A/D conversion can be externally triggered. When the TRGE bit is 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, in both single and scan
modes, are the same as if the ADST bit had been set to 1 by software. Figure 14-6 shows the
timing.
