A built-in PWM DAC is for analog sampling data or voice
signals. The structure of DAC is shown in TABLE 15-1.
There is an interrupt signal from DAC to CPU whenever
DAC data update is needed and the same signal will decide
the sampling rate of voice. In DAC mode, the frequency of
RC oscillator can’t less 2M Hz.
