Temperature sensor connectivity

Hi,

 

We are using IMXD7 application processor (MCIMX7D3EVK10SD ) for our wearable design.  When exploring the options for connecting external temperature sensors with the processor, we found from the datasheet that  we have a pin named TEMPSENSOR_REXT. This pin is recommended to connect to a 100k resistor to ground. Our query is that can we use this pin for external thermistor connection. Can the internal temperature sensor monitor module use this pin for temperature sensing. If yes please provide required inputs for the same.

 

Is there any other recommended way to connect external thermistors to IMX7D processor.

 

Thanks.
