STM32F407 internal pin pulldown in standby?

Hi,

I'm trying to find out whether there is any way to maintain internal pulldowns on pins in standby mode on the STM32F407.

I suspect that this is not the case but haven't been able to find a definitive answer in the documentation. Any help would be appreciated.

Thanks!

According to RM0090 Rev 18, section 5.3.6, all I/O pins are high-impedance in standby mode except for reset, PC13 and PA0, depending on how they are configured.
