A/D Conversion Timing
PWM
The micro-controller provides 4 channels (6+2) bits
PWM outputs shared with PD0~PD3. The PWM chan-
nels has their data register. The PWMs uses a PWM
counter whose stages are 8 (stage 1~stage 8: f
SYS

). The frequency source of the PWM counter co-
mes from f
SYS
. The PWM register is an eight bits regis-
ter. The waveforms of PWM outputs are as shown.
Once the PDi (i=0~3) is selected as the PWMi output
and the output function of PDi is enabled, writing 1 to
PDi data register will enable the PWMi output function.
Otherwise the PDi will stay at 0 . The PWM modulation
frequency, PWM cycle frequency and PWM cycle duty
are summarized in the following table.
