In this datasheet (MKW40Z Reference Manual)   have ADC0_Dm0 pin define is ADC Channel 0 Differential Input negitive.  but FRDM-KW40Z Schematics this pin ADC0_DP0 was used by ADC0_SE1/POT.

so this datasheet (MKW40Z Reference Manual) is old version??

Hi,

Actually both the datasheet & user maunal and schematic are correct. Please make reference from the table of below:

Per the setting of "SCxn[DIFF]= 0", this means that the input will be single ended and there you'll find the DM channels used as single eneded.
