STM32U595 used PA11 and PA12 as gpio

[Sunwaz]

I used PA11 and PA12 as standard GPIO in STM32U595ZJT6Q and system frequency is 4MHz. Config PA11 and PA12 to PP output mode ,no pull up.Don't set this gpios to high, the mini system current is 3mA,but set this gpios to high, the current is 22mA.

Test PA10 or PA0,this current no changed.

I reference RM0456 rev4  13.3.16  and 10.7.12 ,used PA11 and PA12 as standard GPIOS,the USBPWREN and VDD11USBDIS bits in PWR_VOSR must be set.

I config these bit before config GPIO, but this current no changed,still is 22mA.

Hi @Sunwaz ,

Could you please tell me the REV_ID of the devices you used for test (0xE004 4000)?
