The D/A converter includes D/A conversion circuits for two channels, each of which can operate
independently. When DAOE bit in DACR23 is set to 1, D/A conversion is enabled and the
conversion result is output. The following shows an example of D/A conversion on channel 2.
Figure 18.2 shows the timing of this operation.
1. Write the conversion data to DADR2.
2. Set the DAOE2 bit in DACR23 to 1. D/A conversion is started. The conversion result is output
3. If DADR2 is written to again, the conversion is immediately started. The conversion result is
4. If the DAOE2 bit is cleared to 0, analog output is disabled.

result is continued to output until DADR2 is written to again or the DAOE2 bit is cleared to 0.
The output value is expressed by the following formula:
