MODA(pin 3) and MODB(pin 2) pins need to be set high.  This will put it
into Expanded Multiplexed mode.  After a reset it will put addresses
0xfffe and 0xffff into the PC(program counter).  I don't have an EVB,
but I have the technical data on the chip.  You can call motorola
and ask them to send you the technical data manual on the 68HC11A8.
