2. Write a PIC18F assembly language program at address 0x100 to multiply an 8-bit unsigned number in data register 0x50 by 16H. Store the 8-bit result in WREG. Do not use any multiplication instructions. Use ROTATE instruction. Assume that a 'l' is not shifted out of the most significant bit each time after rotating to the left. Also, assume that the 8-bit unsigned number is already loaded into data register 0x40. Write the program Without using a loop b. Using a loop a
