Write the needed assembly instructions to reverse the bytes of a 4-byte integer value that is stored at $1000. For example, reversing $20CAFF31 should be $31FFCA20 1. Write the needed assembly code which defines a 32-bit signed integer variable and set its initial value to-3 2. The TFR transfer instruction copies the contents of one register to another register. The CPU12 has A, B, and CCR as 8-bit registers. X, Y, SP, and D (which is A:B) are 16-bit registers. If the two registers used in TFR instruction have same size, then the copy would work as expected For example: TFR A, B Initial CA Result SF1 CA CA TFRX, Y Initial SF003 Result $78CD SF003 F003 But if we transfer 8-bit register into 16-bit register, then the 8-bit value is sign extended during the transfer. For example, TFR A, Y Initial S7F Result F8CD $007F $85 $85 0167 SFF85 $7F Based on this information, answer the following 2 questions: Write the needed assembly instructions to reverse the bytes of a 4-byte integer value that is stored at $1000.
