STM32F769 Boot base address

Hi,

i need to decide how i connect the boot pin of the STM32F769. If i connect it ground the BOOT_ADD0 is selected as ''boot base address''. The reset value of BOOT_ADD0 defines the ''Flash on ITCM interface'' 0x00200000 as boot address.

Is this address remapped to 0x8000000 where my interrupt vector table is linked to?

What is the difference between using the ITCM and the AXIM interface?

How i can reconfigure it? Is this register reset again when i write a new value to this register and perform a reset? How it can point to another address then?

Thank you.
