• The following program performs an exclusive OR operation on the data at D10 and D20 when XA is ON, and stores the
result at D10.
• The following program compares the bit pattern of the 32-bit data from X20 to X3F with the bit pattern of the data at D9 and
D10 when X6 is ON, and stores the number of differing bits at D16.
