The D/A converter includes D/A conversion circuits for two channels, each of which can operate
independently.
D/A conversion is performed continuously while enabled by DACR. If either DADR0 or DADR1
is written to, the new data is immediately converted. The conversion result is output by setting the
corresponding DAOE0 or DAOE1 bit to 1.
The operation example described in this section 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 DACR to 1. D/A conversion is started and the DA
[3] If DADR0 is written to again, the new data is immediately converted. The new conversion
[4] If the DAOE0 bit is cleared to 0, the DA
output pin. The conversion result is output after the conversion time has elapsed. The output
value is expressed by the following formula:
The conversion results are output continuously until DADR0 is written to again or the DAOE0
bit is cleared to 0.
result is output after the conversion time has elapsed.
