16.3
The D/A converter has two built-in D/A conversion circuits that can perform conversion
independently.
D/A conversion is performed constantly while enabled in DACR. If the DADR0 or DADR1 value
is modified, conversion of the new data begins immediately. The conversion results are output
when bits DAOE0 and DAOE1 are set to 1.
An example of D/A conversion on channel 0 is given next. Timing is indicated in figure 16.2.
1. Data to be converted is written in DADR0.
2. Bit DAOE0 is set to 1 in DACR. D/A conversion starts and DA0 becomes an output pin. The
3. If the DADR0 value is modified, conversion starts immediately, and the result is output after
4. When the DAOE0 bit is cleared to 0, DA0 becomes an input pin.
