Some instruction codes are not defined but do not cause the Undefined instruction trap
to be taken, for instance a multiply instruction with bit 6 changed to a 1. These
instructions must not be used because their action might change in future ARM
implementations. The behavior of these instruction codes on the ARM7TDMI
processor is unpredictable.
The ARM instruction set summary is listed in Table 1-2.
