 I am  using STM32L100

This is put into deep sleep 

so pins are set to input

I am using FET to control power to external devices.  this is connected to PB9  pulled down by 100k resistor.

 I find that the pin has a voltage of 1V.  Does this mean the high impedence is only in order of 250k.  

I can change pulldown but what to keep as high as possible
