Intel Instruction AAD
 AAD 11010101 00001010
Note: The second byte of this instruction is actually the base that the
 instruction is to work with (normally a 10 for BCD operations). If a
 different base is specified, then the instruction will work in that base.
 For example, with a value of 16 it will work in hex. In fact, the
 instruction could be documented as AAD base, a one byte (vice two)
 instruction with one byte of immediate data. This useage is not reliable
 on some other manufacturers microprocessors for example the NEC V20.
