A C program has been compiled into the Atmel AVR assembly
language. The following instruction, which is located at address
0x002A, is executed:
i.) What is the binary value contained in the instruction
register (IR) when the instruction is executed?
ii.) What is the hexadecimal value of the program counter (PC)
when the instruction is executed?
iii.) If register r1 = 0x40 and register r2 = 0x02 prior to
executing the instruction, what are the contents of r1 and r2...

Please help by showing steps.
Question 4. (continued) (b) Consider a 16-bit binary number stored in AVR registers r15:r14 which the programmer considers to be a two's complement value. (r15 holds the most significant byte, r14 holds the least significant.) Write down a sequence of AVR assembly language instructions which perform each of the following operations The result should end up in r15:r14. Other registers can be used freely if required i) Sets r15:r14 to the constant value-1 (2 marks)...

The following 32-bit hexadecimal number describes a RISC-V machine instruction. Decode this instruction into a RISC-V assembly language statement (like `add x0, x1, x2`). To receive partial credit, you should show your steps including converting to binary format and identifying opcode, funct3, rs1, etc. 0x00C1F963

Use HCS12 assembly language only - not C code Using CodeWarrior to create a new project that uses assembly language. Write an assembly program that turns on the red LED at the beginning. It switches to off 2 seconds later and switches back to on after three more seconds. (That is, it stays on for 2 seconds and off for 3 seconds.) This switching process lasts forever. Use a loop (or nested loops) for each of the 2/3-second delay where...
