19.6.5
A/D conversion can be externally triggered. When the TRGE1, TRGE0 bits in ADCR are set to 1.
external trigger input is enabled at the ADTRG pin. A high-to-low transition at the ADTRG pin
sets the ADST bit in ADCSR to 1, 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 19.9
shows the timing.
19.7
The A/D converter generates an interrupt (ADI) at the end of A/D conversion. The ADI interrupt
request can be enabled or disabled by the ADIE bit in ADCSR.
