The D/A converter includes D/A conversion circuits for two channels, each of which can operate
independently. When the DAOE bit in DACR01 is set to 1, D/A conversion is enabled and the
conversion result is output.
An operation example of D/A conversion on channel 0 is shown below. Figure 20.2 shows the
timing of this operation.
1. Write the conversion data to DADR0.
2. Set the DAOE0 bit in DACR01 to 1 to start D/A conversion. The conversion result is output
3. If DADR0 is written to again, the conversion is immediately started. The conversion result is
