Suppose r8-0XFFFFFFFF, r1 8x00000001, and r2 = 0x00000000. Initially N, Z, C, and V flags are zero. Find the value of the N, Z, C, and V flags upon executing the following instructions. (Assume each instruction runs individually, i.e. these instructions are not part of a program.) Do NOT use the debugger as you are expected to reason and conclude values for the flags. (1) ADD r3, re, r2 (2) SUBS r3, re, re (3) ADDS r3, re, r2 (4) LSL r3, r0, #1 (5) LSRS r3, r1, #1 (6) ANDS r3, re, r2
