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 23.2 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
4. If the DAOE0 bit is cleared to 0, analog output is disabled.

result continues to be output until DADR0 is written to again or the DAOE0 bit is cleared to 0.
The output value is expressed by the following formula:
