Write assembly that is functionally equivalent to the following operations from the bare metal part of lab 1. 1. Configure the port that is connected to the blue LED PB7 as an output 2. Configure the port that is connected to the user switch PC13 as an input 3. Read the switch leaving its value in RO in the bit 0 position 4. Write the blue LED with the contents RO bit position 0 You SHOULD preserve the register contents that you are not changing (think of how we used bit manipulation to only affect the desired bits of the registers). We are not going to worry about writing the OTYPER register for this part given that the default reset values will work.
