APB Pulse Width Modulator (70129)
The APB PWM Module is a standard APB peripheral that generates a programmable duty cycle output signal. The frequency of the output waveform is either PCLK/256 or PCLK/4096, depending on whether a 4-bit prescaler is enabled. The duty cycle can be programmed with 8-bit resolution from either the APB interface or from an external controller interface. The output can be disabled or enabled. Disabling resets the counter to zero for the next enable.
