For motor control and swich mode power supply application, it is required that the ADC sampling is synchronized with PWM signal. In general, most Kinetis sub-family provides FTM, PDB and ADC, it provides a mechanism for ADC converter is synchronizedc with PWM signal.

But the KEA family does not have PDB module, instead, the KEA family provides a simple mechanism which enables PWM signal the FTM module generate can synchronize the ADC converter.

The DOC introduces the mechanism, give the register configuration description, code and scope screenshot on how the PWM signal synchronizes the ADC.
