PWM can be used for generating analog signals of frequency very much lower than that of the PWM frequency. LPC1768 has one PWM with six channels. There will be one timer for each PWM and this timer will be used by all channels of that PWM. Configuring the PWM is similar to that of configuring a timer. The only difference is that we also need to specify the location of rising and falling edges for each channel that we use.
