b$)$ A simple AVR C$-$program is shown below in figure $3$b$.$ The assembly

language output from the $C$ compiler is also shown on the right hand side of

figure $3b.$ Answer the following questions:

i$.$ Complete the assembly language program on the right hand side of

figure $3b$ below, if the variables $x,y$ and $z$ are stored at address

$0100,0101$ and $0102$ respectively?

$(6$ marks$)$

ii$.$ In assembly language program explain how the variable $"y"$ gets

initialised to $022?$ Explain the operations that are required to

initialise the variable $"y".$

$(4$ marks$)$

iii. Explain where in the CPU the result from the ADD instruction will be

stored after the ADD operation is executed?
