15.4.4

External Trigger Input Timing

A/D conversion can be externally triggered. When the TRGS1 and TRGS0 bits are set to 11 in

ADCR, external trigger input is enabled at the

ADTRG pin. A falling edge 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 has been set to 1 by software. Figure 15.6 shows the

timing.
