15.4.4
A/D conversion can be externally triggered. When the TRGE bit is set to 1 in ADCR and the 8-bit
timer's ADTE bit is cleared to 0, 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 had been set to 1 by
software. Figure 15.6 shows the timing.
15.5
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. The ADI interrupt request can be
designated as a DMAC activation source. In this case, an interrupt request is not sent to the CPU.
