I am confused about the concept of using a pin offset in bit banding. EG, given that PORTA has a base address of 0x40004000 and the 5th bit has an offset of 0x0080, the address of the pin should be 0x40004080 and I use this address to read/write to this bit.
My questions are :
1 - Is this address in the 1 MB bit band region or it's in the alias ?
2 - How can the sum of two different bins offsets + the base port address allows us to write to the two pins simultaneously? is it some sort of a mask ?
sorry if my questions are not clear, I am really confused.
