External Trigger Input Timing
A/D conversion can also be started by an external trigger input. When the TRGE bit is set to 1 in
ADCR, external trigger input is enabled at the
ADTRG
pin. A falling edge at the
ADTRG
input
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 when the bit ADST has been set to 1 by software. Figure 14-3
shows the timing.
