MUST USE STM32CubeIDE using board STM32F401RET6.

Modify the main body of your project, main.s, such that it performs the following mathematical operation.

a. Using the last 6 digits of your student ID number, load the first two digits to register 1, the next two digits to register 2, the last two digits to register 3. For example, if the last 6 digits of your student ID are 930582, then your three registers will store as follows: 1 = 93, 2 = 05 and 3 = 82.

b. Using the three register values, write a series of mathematical operations in assembly code which result will be the last 6 digits of your student ID number, saved in register 0. - Using the example digits from part a, this means that after all the operations the content of register 0 will be 0 = 930582. - You are explicitly prohibited from manually assigning your student ID number to register 0. - You may use the additional registers available to have additional values needed in your mathematical operation.

Code that must be modified.
