The above is an example where 16 bit width, OR mode, bus break 1 with zero break count are set. A break

In this example, condition 2 is added without changing condition 1.
A break occurs when 0x12 or 0x13 is read from address 0x200000, even though the previous condition is
set to occur only when 0x12 is read from address 0x200000.
