Please answer the following questions:

1. DELAY_VALUE_1 EQU 0X01FF

The purpose of this line is: (select best choice)

A. To define a constant called DELAY_VALUE_1 with the value 511 in decimal

B. To define a constant called DELAY_VALUE_1 with the value 512 in decimal

C To create a one byte variable that is initialized to the value 0xFF

D. To create a two byte (one word) variable that is initialized to the value 0x01FF

E. It is an assembler directive which sets the address counter to 0x01ff

F. To create a space froa table or array in RAM space with the name DELAY_VALUE_1

G. None of the above

2. What is the value of BufferTableSize in this case (in decimal):

ORG 0200h

BufferTable DS 32

BufferTableSize EQU $-BufferTable

3. The following code is a part of the program from problem 2. The value of 0 is copied to somewhere. What address is it copied to?

mov #0200h, R14

mov.b #0, 0(R14)

4. How many times does this loop execute?

LoadDelay mov.w #000Ch, R15

LoopTop dec.w R15

jnz LoopTop

Done

5. Suppose the state of bits at P1OUT are 11001011 and the following line is executed:

xor.b #0Ch, &P1OUT

What is the new state of bits at P1OUT?

6. Execute the following lines. What is the final value in R12? (note R12 is a 16 bit register, please show the full 16 bits of content)

mov.w #4739h, R9 (note this is a word mov)

mov.b R9, R12 (note this is a byte mov)

7. Suppose SP contained the value 0x0400 and the following instruction is executed:

mov.w #02467h, R12

push.b R12 (note this is a byte operation)

What is the value in SP? (in hexadecimal)

What is the byte value stored at the top of the stack? (in hexadecimal)
