Write an AVR assembly program to shift a 32-bit number left for 4 positions (4 bits). Assume the 32-bit number is already initialized in data memory 0x200 to Ox203, and labeled "buf. Use a loop to perform the operation. Use "Ipcnt" as your loop counter. There is no restriction on what loop construct to use. Use the 2. proper assembler directives.cseg.dseg,.org, .byte, .def, and or .equ, to set up the proper operation environment. There is no need to store the result into data memory.
