Question 1. Write a program sequence that places the value in Address $2000 into Accumulator A and places the value in Address $2001 into Accumulator B. Then, add these values together and store the result in Location $2002.

Question 2. Where is the return address of the subroutine stored when a subroutine is called? How is this return address retrieved at the end of the subroutine?

Question 3. Write a C statement to set Bit 3 of variable foo without changing other bits.

Question 4. Write a HCS12 assembly-language program that counts all even numbers from a 10-variable, byte-sized array and moves the odd numbers to a new array.

Question 5. Write a C program for a HCS12 microcontroller that writes the value, 0x78, to Memory Location VAR1 and then calls a delay function. The delay function should generate a delay of 0.25 milliseconds. Then, send the pattern 0x99 to Memory Location VAR2 and call the delay function one more time. Repeat this operation eight times using a for loop. Assume that the bus clock frequency is 24MHz. Write the delay using inline assembly language.
