Over consumption with GPIO input

Hi,

I'm trying to have the lowest consumption I can with a very simple design.

Weird thing appenened:

Putting PD4 in ''floating no interrupt'' mode, give me a definitely higher consumption than ''output pull-push low level'' mode (~150uA more)!

Regards,

There is the answer:

CLK_PeripheralClockConfig(CLK_Peripheral_ADC1, ENABLE);

ADC1->TRIGR[2] = 0xFF; // disable triggers

CLK_PeripheralClockConfig(CLK_Peripheral_ADC1, DISABLE);
