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
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 17-6 shows the
timing.
