Has anyone worked with the KL28's ADC but not using its internal asynchronous clock source?
The NXP examples that I have seen all use the ADC's internal clock rather than a PCC selected clock source but I haven't been able to get the ADC to calibrate when connecting other sources (bus clock, fast IRC, etc.) although I believe that they should be correctly in range. When I use the internal clock source it does operate.
The KL28 is one of the first with a PCC and SCG to control clocks and peripheral clock sources, whereas I never had issues with using the bus clock in many other parts.
Anyone know the trick needed!
