16.4.4
External Trigger Input Timing
It is possible to start A/D conversion from an external trigger input. External trigger input is input
from the
ADTRG
pin or MTU when the TRGE bit of the A/D control register (ADCR) is set to 1.
A/D conversion is started when the ADST bit of the A/D control/status register (ADCSR) is set to
1 by the
ADTRG
input pin last transition edge or MTU trigger. Other operations, regardless of
whether in the single or scan mode, are the same as when setting the ADST bit to 1 with the
software.
Figure 16.6 shows an example of external trigger input timing.
