Which ARM7TMI microprocessor register contains the four flags (C, V, N and Z flags) and what are their main functions? What are the values of flags C, V, N and Z after the following sequence of instructions are executed? Assume that initially all flags are RESET (set to Zero). MOV r2, #15 MOV r3, #10 MUL r4, r3, r2 ADDS r2, r4 MOV r4, #20 SUB r4, r3 Question No. 1 continues on page 2. 1 EE3002 What will be the values of flags (C, V, N and Z) if instruction ADDS is changed to ADD in the above sequence of instructions? Briefly explain the purpose of "S" suffix in ARM7TMI microprocessor. (15 Marks)
