Explanation of Example: Prior to execution, the 56-bit A accumulator contains the
value $FF:FFFFFF:FFFFFF, and the 24-bit X0 register contains the value $234567. The
execution of the MOVE X0,A1 instruction moves the 24-bit value in the X0 register into
the 24-bit A1 register without automatic sign extension and without automatic zeroing.
