Question $1$: Write a piece of code using Assembly language to perform the shown logic circuit

in Figure $1.$ For that, $A=A2H,B=F3H$ and $R_0=98H.$ Show the output of each gate in

hexadecimal.

Also, sketch the flow chart of the process.

Question $2$: Write a piece of code using Assembly language to make the lower $4-$bits of the

LEDs shown in Figure $2$ blinking as per the criteria below:

a$.$ First, Count$-$Down from $(15{)}_{10}$ to $(0{)}_{10}.$

b$.$ Second, Count$-$Up from $(0{)}_{10}$ to $(15{)}_{10}.$

c$.$ Third, steps a to b must repeat sequentially.

Also, sketch the flow chart of the process.
