Hello, I am trying to measure the power consumption of the STM32U575ZI microcontroller on the Nucleo-144 board but the results are much higher than expected.

 I am using an ammeter connected instead of the JP5 jumper, as indicated in the manual (UM2861) and tried several examples.For example: in PWR_EnterStopMode example I see around 568uA on the ammeter.From the datasheet I expected to measure around 100...
