title: Current consumption of the uC on a STM32 Nucleo-64 evaluation board
body: <p>I want to measure the current consumption of the uC on my STM32 Nucleo-64 evaluation board (NUCLEO-L073RZ). The manual says, that I just have to remove the JP6/IDD jumper and then connect the pins to an ammeter:

  <p>But if I just remove the JP6 jumper (no pin connection), the uC is still running (I can still debug/communicate via I2C). I would have expected, that if the JP6 is removed, the uC is no longer powered and therefore not accessible anymore...</p>
  
  <p>Can somebody please explain me, where is my error in reasoning?</p>
