I am working with the MC68HC908JL16 and I have a problem with converter ADC.
I use 2 inputs of the converter and if while I make the conversion of an input I enter signal by the other the measurement varies.

I believe that it is a problem of the configuration of the ADC, since with the MC68HC908JL8 it happened to me the same and when modifying the configuration the problem I am solved. But now with himself not to solve the problem.
I have an external crystal of 16 and want to make the conversion of 10 bits.
As I must program the converter?
