hey so I'm having some trouble understand 3 fairly simple lines of code configuring some port D pins i know somehow they are supposed to make pins 0-3 and 8-15 as 2MHz low speed outputs with a pull-up resistor on pin 0 but after looking thru the c and h files I'm just not sure how to get to that conclusion can someone help me out please?
GPIO->OSPEEDR = 0xFF00; GPIO->PUPDR = 0x1; GPIO->MODER = 0x5555;
Thank you!

Well there's the whole of Chapter 8, about GPIO
And this section 8.4 "GPIO Registers" bit around page 278 that would appear particularly salient.
