14.4.4
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
low transition at the
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.
14.5
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.
