1. For each question, choose the option that shows all changes that executing one instruction would make to the state of the machine (i.e. memory, registers, PC, and CC the condition code register).

Register Initial Contents R0 x3000 R1 x3001 R2 x6002 R3 x6011 R4 x6000 R5 x6010 R6 x3004 R7 x4014 PC x3000 CC n Address Symbol Initial Contents x3000 LDI R6, far x3001 AND R1, R2, R7 x3002 HALT x3003 far x6000 x3004 x4321 ... x6000 xf000 x6001 404 x6002 808

1)PC = x3003, R6 = x6000

2)PC = x3001, R6 = xf000

3)PC = x3001, R1 = x4000

4)PC = x3003, R6 = xf000
