1. Memory location $1000 contains an unsigned value. What instruction or instruction sequence will load that value into index register X?

2. Memory location $1002 contains an unsigned value. What instruction or instruction sequence will load that value into accumulator D?

3. What instruction will set the contents of index register X to zero?

4. What two different instructions will each set the contents of accumulator A to zero while affecting no other registers?

5. What two different instructions or instruction sequences will copy the signed byte value at memory location $1000 to the byte memory location $1001?

6. Without using any accumulator or index register, what instruction or instruction sequence will copy the unsigned byte value at memory location $1000 to the word starting at memory location $1002?

7. What instruction or instruction sequence will copy the signed byte value at memory location $1000 to the word starting at memory location $1002?

8. Accumulator A contains a value in the range 10 through 100. Can the value be considered signed? Can it be considered unsigned?

9. Accumulator B contains a value in the range 10 through 150. Accumulator A contains the value 0. If the value in accumulator D is considered to be signed, does the value in accumulator D equal the value in accumulator B?

10. A byte value in the range -10 to -1 is added to a byte value in the range 50 to 128. Can the sum be considered to be signed? Can it be considered to be unsigned?

11. Write a code sequence which will increment the four byte value at location $1020 through $1023. The value is stored in big-endian order.

12. Write a code sequence which will add the three byte unsigned integer value stored in locations $1000 through $1002 into the three byte unsigned integer value at locations $1100 through $1102. The values are stored in big-endian order.
