(Watch what happens to register X.) g) After line 9, what are the contents of JOBO and JOBO+1? h) After line 13, what are register A, B, X, and Y equal to? i) After line 15, what data is in TEMP+1? j) Describe the operation of line 19. k) Identify the condition code flag settings after line 19. N= Z= V= C= l) Is the branch in line 20 taken or ignored? Why? m) After the code has run, identify the contents of each DATA memory location listed below: DATA1_________ DATA2_________ TEMP________ TEMP+1 ________ TEMP+2 ________ JOBO________ CLEM _________ BOBO _________ JIMI ________ 2. Write a program with the following characteristics: Data memory starts at $D000 Code memory starts at $A000 Two constants, ($24, $35) should be placed into data memory using the FCB directive and the symbol names INPUT1, INPUT2. Two memory bytes, (SUM, DIFF) should be reserved using the RMB directive. PART1 of the program code should perform an addition of the two constants and store the result in SUM. This part should be done using EXTENDED addressing mode for all memory access operations. PART2 of the program should perform a subtraction of the constants, where the contents of INPUT1 are subtracted from that of INPUT2. This part should use INDEXED addressing mode for all memory access operations.
