Boot0 internal connection

Hi!

I've 4 STM32 processors on my board that are all connected on the boot0 pin with each other without a series resistor. This common boot0-signal is set or reset by another microcontroller and so I can select the boot mode (boot1 is pulled down with a 10k resistor). Now, I've to calculate a series-resistor for this common boot0-signal. How is the boot0-pin configured at startup?? are the pull-down or pull-up resistors activated??

Thank you very much!!
