b) Consider the AVR assembly code given in Listing 1. i. All instructions in the program are 2 bytes long. What is the size of the code in bytes? ii. Explain the function of the symbols '@0' and '@1' in the code. iii. Determine the maximum delay this code can generate. Show all your workings. Assume the processor is operating at 8 MHz Listing 1 .MACRO delay Idi @0,@1 loop: nop nop nop nop .ENDMACRO dec @0 brne loop.
