Table 17.3 Control of D/A Conversion
17.4
The D/A converter includes D/A conversion circuits for four channels, each of which can operate
independently.
When DAOE bit in DACR01 or DACR23 is set to 1, D/A conversion is enabled and the
conversion result is output.
The operation example concerns D/A conversion on channel 0. Figure 17.2 shows the timing of
this operation.
[1] Write the conversion data to DADR0.
[2] Set the DAOE0 bit in DACR01 to 1. D/A conversion is started. 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 is continued to output until DADR0 is written to again or the DAOE0 bit is cleared to 0.
The output value is expressed by the following formula:
