Functional Description
7.4.1.5 ADC Triggering
In cases where the timing of the ADC triggering is critical, it must be scheduled as a
hardware event instead of software activated. With this PWM module, multiple ADC
triggers can be generated in hardware per PWM cycle without the requirement of another
timer module.
complementary mode of operation, only two edge comparators are required to generate
the output PWM signals for a given submodule. This means that the other comparators
are free to perform other functions. In this example, the software does not need to quickly
respond after the first conversion to set up other conversions that must occur in the same
PWM cycle.
