Configure PB 2 Output Type as No Pull-up no pull-down

Answer 1

Answer is as follows :

As in given scenario, some of the bits are already set.

So according

The value of given MASK accordingly to bitwise clear, we need to set the bits at 0 which are described as #.

So in this way we get

0000 0000 0000 0000 0000 0000 0000 0000 (where bold bits are predefined)

So it is equal to

0x00000000 in hexadecimal

So GPIOB pull up pull down register mask (bitwise clear) = 0x00000000

if there is any query please ask in comments...
