Hello, I am using MPC5644A microcontroller with 20 MHz and 40 MHz crystals. When I used 20 MHz with the MPC5644A, I read the some values from the ADC channel but when I use the 40 MHz crystal with same code, I cannot read any value from the ADC channels, I checked my power and ADC signals and did not see any problems. I checked the pins of the MPC5644A but did not see any issues, do you know why I am seeing this problem? Can you help me ?
Thank you,
Bülent
