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)...
