Note: All assembly code should be well commented-similar level of detail to samples. 7. Write ARM code that decodes the immediate value in an instruction-takes the last 12 bits and turns it into the value it represents a. Start by loading r1 with the value E3A01CFA (machine code for a move immediate into register) b. Isolate bits 0-7 (the rightmost 8 bits) the 8-bit binary number - into r2 c. Isolate bits 8-11 d. Multiply r3 by 2 to get the actual rotation amount e. Rotate r2 to the right by that many bits. Place your answer in r4 (the four bits left of 0-7)-4 bits indicating the rotation- into r3
