Hello,

You can check in the schematics:

http://cache.freescale.com/files/soft_dev_tools/hardware_tools/schematics/TWR-KL25Z48M_SCH.pdf?fpsp=1&WT_TYPE=Schematics&WT_VENDOR=FREESCALE&WT_FILE_FORMAT=pdf&WT_ASSET=Downloads&sr=0

Connected to PTE29/ADC0_SE4B.

In the SC code there is an adc16 driver code and an example of using ADC.

I think, at least is a starting point.

Best Regards,

Luis
