* Silly question, I'm writing a certain type of driver for the first time

I want to have something like `static mut MY_DRIVER : MyDriver = MyDriver { pointer_to_a_register : ... };`

When I try to supply a pointer for my feild `ndtr : &NDTR` I get an error about a dangling pointer

It seems like the STM32 register access crates make it really hard to get a pointer at compile time.
