STM32H735 Wake Up pull configuration STANDBY mode

I am configuring wakeup pin PA0 to WAKEUP1 by wirting 01 (pull-up) at WKUPPUPD (PWR_KUPEPR) as said at RefManual by using "HAL_PWREx_EnableWakeUpPin ".

 

PWREx_WakeupPinTypeDef sPinParams;

sPinParams.PinPolarity = PWR_PIN_POLARITY_LOW;

sPinParams.PinPull = PWR_PIN_PULL_UP;

sPinParams.WakeUpPin = PWR_WAKEUP_FLAG1;

HAL_PWREx_EnableWakeUpPin (&sPinParams);

 

After that i go to standby mode by using:

HAL_PWR_EnterSTANDBYMode();

 

Then at standby mode, there is no pull up at PA0.

At the manual it is said that the pull up config is kept at standby mode.

Do i have to do something else?

 

Thanks!!
