The D/A converter incorporates two channels of the D/A circuits and can be converted
individually.
When the DAOE bit in DACR is set to 1, D/A conversion is enabled and conversion results are
output.
An example of D/A conversion of channel 0 is shown below. The operation timing is shown in
figure 17.2.
1. Write conversion data to DADR0.
2. When the DAOE0 bit in DACR is set to 1, D/A conversion starts. After the interval of t
3. Conversion starts immediately after DADR0 is modified. After the interval of t
4. When the DAOE bit is cleared to 0, analog output is disabled.
conversion results are output from the analog output pin DA0. The conversion results are
output continuously until DADR0 is modified or the DAOE0 bit is cleared to 0. The output
value is calculated by the following formula:
conversion results are output.
