MTU Trigger Input Timing

It is possible to start A/D conversion from an MTU trigger input. MTU trigger input is input from

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 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 14.6 shows an example of external trigger input timing.
