Section 16 D/A Converter
Table 16.2 D/A Conversion Control
16.4
Two channels of the D/A converter can perform conversion individually.
When the DAOE bit in DACR is set to 1, D/A conversion is enabled and the conversion results are
output.
An example of D/A conversion of channel 0 is shown below. The operation timing is shown in
figure 16.2.
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

the conversion results are output from the analog output pin DA0. The conversion results are
output continuously until DADR0 is modified or DAOE0 bit is cleared to 0. The output value
is calculated by the following formula:
(DADR contents)/256 × Vref
conversion results are output.
When the DAOE bit is cleared to 0, analog output is disabled.
