The fast clock is used to provide as PWM driver time base, and user shall set the PWMC[7]=’1’ and
VOC[2]=’1’ to enable the PWM output. When the system enters into sleep or idle mode, it will
automatically turn off the voice device by clearing VOC[2:0] to ”000”. In order to activate voice output
again when the system returns and enter into normal mode, the related bits of VOC register need to be set
again.

When the DAC is used as sound generator, the bias & filter circuit is used for bias voltage setting and
waveform filter regulation and the DAC is output to the VO (Voice Output) pin and please see application
notes for detailed calculation example and application. The driving capability of DAC is shown below.
