Problem 2 - Subroutines Write an ARM assembly program for the function bit isolation. This function accepts a 32 bit number, two unsigned integers: lower and upper, separates the bits between lower and upper limits and returns these bits. You must follow ARM Procedure Call standard. Add comments to your code. The following is a few examples of this function. Bit isolation 0x12345678, 0, 8} returns 0x78 Bit_isolation (0x12345678, 8, 12) returns 0x6 Bit_isolation (0x12345678, 30, 32) returns 0x0
