A/D conversion can also be started by MTU trigger input. When the TRGE bit is set to 1 in the
A/D control register (ADCR), input from the MTU functions as trigger input. When an MTU
trigger is detected, the ADST bit is set to 1 in the A/D control/status register (ADST), and the A/D
converter is started.
Other operations, for both single mode and scan mode, are the same as when the ADST bit is set
to 1 by software, .
Figure 13.6 shows the timing for MTU trigger input.

The A/D converter converts analog values input from analog input channels to 10-bit digital
values by comparing them with an analog reference voltage. In this operation, the absolute
precision of the A/D conversion (i.e. the deviation between the input analog value and the output
digital value) includes the following kinds of error.
1. Offset error
2. Full-scale error
3. Quantization error
4. Nonlinearity error
